Everything you need to know about IP55 classified motors for outdoor use – from selection criteria to specific application cases.
What does the IP55 protection class specifically mean for a motor used outdoors?
A motor with IP55 protection is protected against dust in harmful amounts (first digit 5) and provides protection against water jets from all directions (second digit 5). This means it can withstand rain and spraying with a hose, but is not suitable for submersion.
Is an IP55 motor automatically the best solution for every outdoor application?
No, not necessarily. While IP55 is sufficient for many scenarios such as conveyor systems exposed to rain, applications with high-pressure cleaning may require IP66 or in flood risk IP67/IP68. A precise analysis of the environmental conditions is crucial for the correct and economical selection..
Which standards define the IP protection classes like IP55?
The IP protection classes are established by international and national standards, primarily the DIN EN 60529 (VDE 0470-1). It is important to pay attention to the publication date of the standard, as testing conditions and definitions may change over time.
When should I consider a higher protection class than IP55 for my outdoor motor?
A higher protection class is necessary when specific risks exist: IP66 for strong water jets (e.g., pressure washers), IP67 for temporary submersion, and IP68 for permanent submersion of the motor. For very dusty environments, IP6X (dust-tight) can also be advantageous.
What is the IK protection class and why is it important for outdoor motors?
The IK protection class indicates the impact resistance of the motor housing against mechanical impacts. This is especially relevant in outdoor areas, where motors may be exposed to vandalism or falling objects. An IP55 motor can, for example, additionally have an IK08 classification for increased robustness.
Can I additionally protect an IP55 motor for particularly harsh outdoor conditions?
Yes, protection can often be enhanced. Measures such as additional protective covers against direct sunlight or heavy precipitation, special housing coatings against corrosion or the use of heated condensate protection devices can extend the lifespan.
What should I pay particular attention to when installing an IP55 motor outdoors?
Die correct sealing of the cable connections is absolutely critical. Use fittings that correspond to at least the IP class of the motor and tighten them according to the manufacturer’s specifications. Improper installation can invalidate the IP protection..

Understand: Optimally utilize IP55 motors in outdoor use.
Understanding the basics
The designation IP55 is relevant for outdoor use, but not universally applicable. Many users assume that IP55 is sufficient for every outdoor application, but specific environmental conditions are crucial. Ein IP55 motor is suitable, for example, for a conveyor system in the outdoor area of a logistics center under rain exposure, as long as no high-pressure cleaning occurs. Gear Box motors for outdoor areas often require this protection.
Initial considerations
Several factors need to be considered before deciding on the motor. The distinction between IP protection rating and electrical protection class of the motor is important. A motor can have IP55 and additionally require a specific electrical protection class (e.g., Class I) for protection against electric shock. Electric motors with brakes in outdoor areas also benefit from clearly defined protection classes.
Relevance for your application
Ein IP55 motor for outdoor use is not always the best or most cost-effective solution. Not every outdoor application requires the same level of protection; often a different IP class is more economical or technically sensible. For applications under a canopy with only occasional splashing, IP44 may be sufficient, while areas with strong water jets require IP66.Decrypt: Mastering the IP55 protection class and its standards
Decoding the digits
The digits in “IP55” have specific meanings. The first ‘5’ stands for dust protection (limited ingress, no harmful deposits), the second ‘5’ for protection against water jets from all directions. This protects against rain or spraying with a garden hose, but not against submersion (for that IP67 is needed). IP65 classified Gear Box motors offer higher dust protection.
- The first digit ‘5’ in IP55 marks the protection against dust, meaning that limited ingress of dust is permissible without harmful deposits occurring.
- The second digit ‘5’ in IP55 defines the protection against water jets that strike the housing from any direction.
- Thus, IP55 provides protection against rain or the water jet from a garden hose, but is not designed for submersion of the motor (for this, at least IP67 would be necessary).
- The exact requirements and testing procedures for IP protection classes are defined in international and national standards, such as DIN EN 60529 (VDE 0470-1).
- It is important to note the publication date of the relevant standards, as definitions and testing conditions can change over time.
- IP55 is not suitable for applications that require permanent submersion (protection class IP68) or protection against very strong water jets (protection class IP66).
- A careful analysis of specific environmental conditions and requirements is essential to select the correct and most economical IP protection class.
Normative foundations
IP protection classes are defined by standards. It is important to refer to specific standards such as DIN EN 60529 (VDE 0470-1) and to note their publication date, as definitions may change. Testing procedures for water jets in older standards may differ from current versions (e.g., DIN EN 60529:2014-09).
Distinction from other protection classes
The suitability of IP55 depends on the conditions. An IP55 motor is not designed for permanent submersion (IP68) or very strong water jets (IP66); a precise needs analysis is necessary. A pump in a flood-prone pit requires at least IP67, while a motor with IP55 protection for outdoor use is often sufficient in the rain protection.Assess: Check the suitability of IP55 motors for your outdoor application
Typical application scenarios
IP55 motors are suitable for many outdoor applications.. They perform well in devices such as external ventilation systems or pumps that are exposed to weather influences but not extreme conditions. A motor for a conveyor belt under an open canopy that must withstand occasional rain is well protected with IP55. Temperature-tolerant Gear Boxes can be a sensible addition.
Limits of load capacity
IP55 motors have limits in outdoor use, capacity. Applications with high-pressure cleaning or occasional submersion of the motor exceed the capacities of the IP55 protection. A motor in a car wash, for example, requires at least IP66 to withstand strong water jets.
Additional protective measures
The protection of an IP55 motor for outdoor applications can be improved in the field. Measures such as an additional protective roof or a special housing coating can extend the lifespan in harsher environments. A small metal roof above a motor in sunny or rainy regions reduces thermal load and direct water exposure. Corrosion-resistant motors are another option.Selecting: Finding the right IP55 motor based on clear criteria
Analyze environmental conditions
When selecting a IP55 motor for outdoor applications motor, environmental influences must be taken into account. In addition to dust and water, ambient temperature, humidity, and chemical loads are crucial for material selection and sealing technology. A motor near the coast may require additional corrosion protection due to salty air, despite being rated IP55. Thermally protected motors are relevant at high ambient temperatures.
- Analyze the ambient conditions in detail: In addition to dust and water, ambient temperature, humidity, and possible chemical exposure also play a role in material selection and sealing technology, especially for a motor designed for outdoor use.
- Consider mechanical robustness: The IK protection rating (impact resistance of the housing) is an important factor, especially where there is a risk of vandalism or falling objects that could damage the motor.
- Define electrical and performance requirements precisely: Voltage, frequency, required power, and the desired energy efficiency class (e.g., IE3, IE4) are fundamental for optimizing operating costs and performance.
- Check manufacturer-specific options and special models: Providers like Focquet offer subtypes such as the MF*T series with increased power density for limited installation space or multiposition motors for flexible mounting options.
- Pay attention to the material selection of the motor housing and the quality of the sealing technology to ensure a long service life under the given environmental influences.
- Consider additional corrosion protection, even for IP55-rated motors, if operation in aggressive environments such as coastal areas (salty air) is planned.
Mechanical robustness
The IP classification alone is not always sufficient for mechanical stress. The IK protection rating (impact resistance of the housing) is an important factor, especially in cases of vandalism risk or falling objects. Ein Outdoor motor with IP55 classification in public areas may additionally require IK08 for impact resistance. Focquet considers this aspect in its motors.
Electrical and performance requirements
Electrical parameters and performance features are relevant for the application. Voltage, frequency, power, and energy efficiency class (e.g., IE3, IE4) are the fundamentals for optimizing operating costs and performance. A motor for continuous applications should have a high efficiency class (e.g., IE4) to reduce energy costs.
Manufacturer-specific options
Different manufacturers offer different advantages. Focquet, for example, offers subtypes such as the MF*T series with increased power density for limited installation space or multiposition motors for flexible mounting. Such variants can better meet specific requirements than standard models.Benefit: Learn about manufacturer diversity and specific product advantages
