Powerful, efficient, and versatile – everything you need to know about this industrial motor.
What is the difference between nominal and synchronous speed in a 2.2 kW 3000 RPM motor?
Die Synchronous speed (e.g., 3000 RPM) is the speed of the magnetic field at no load. The nominal speed (e.g., approx. 2895 RPM) is the actual speed of the motor shaft under full load and takes slip into account.
Which design (B3, B5, B14) is right for my application with a 2.2 kW motor?
The choice of design depends on the type of mounting: B3 is a foot mount, B5 is a flange mount (large flange) und B14 is also a flange mount (small flange). There are also combined designs such as B34 or B35. The exact dimensions (e.g., shaft diameter Ø24 mm for size 90) are critical.
Is an IE3 three-phase motor with 2.2 kW and 3000 RPM always the best choice?
Not necessarily. While IE3 motors are more energy-efficient (e.g., 85.9% efficiency), they can be problematic due to higher starting currents and mass inertia in applications with frequent switching operations or in retrofits of older systems. Here, an IE2 motor or a special series may be more suitable.
What does S6 operation mean for a 2.2 kW three-phase motor and when is it relevant?
S6 operation (temporary operation with intermittent load) means that the motor is operated cyclically with load and no-load phases or standstill phases, without reaching thermal stability. This is typical for applications such as sawing, drilling, or lifting equipment. Proper design and appropriate motor protection are particularly important here.
How do I optimally protect my 2.2 kW three-phase motor from overload?
Modern motors often feature integrated PTC thermistors (NTC) in the windings. For comprehensive protection, especially in S6 operation, a motor overload relay with undervoltage trip is recommended, as standard overload relays may be insufficient here.
What rated current and power factor should I expect with a 2.2 kW, 400V, 3000 RPM three-phase motor?
A typical 2.2 kW three-phase motor (400V, approx. 3000 RPM, size 90) has a rated current of about 4.3 Amperes and a power factor (cos φ) of approximately 0.85..
Can I simply replace an existing 2.2 kW three-phase motor with an IE3 model?
A simple 1:1 replacement is not always advisable. IE3 motors often have higher starting currents, which may require adjustments to protective devices or supply lines. It is important to check the compatibility with the existing system to avoid failures or damage.
What degree of protection (e.g., IP55) is necessary for a 2.2 kW three-phase motor in my industrial environment?
The standard degree of protection is often IP55, which provides protection against dust accumulation inside and against water spray from all directions. For harsher environments or special requirements (e.g., food industry), higher degrees of protection such as IP66 or stainless steel housings may be required.
Choosing the right three-phase motor 2.2 kW 3000 RPM requires more than just matching rated power and speed; consideration of operating mode (e.g., S6 for intermittent loads) and the appropriate efficiency class (IE2/IE3 depending on the application) is critical for optimal performance and avoiding up to 90% of failures due to poor planning.
Technical details such as rated current (approx. 4.3 A at 400V), power factor (approx. 0.85) and available designs (B3, B14, B35) are essential for correct design and integration. A proper motor overload protection, e.g., through PTC thermistors and motor overload relays, significantly increases operational safety. IE3 motors offer

This motor variant, such as the M3A-90L-2 from Updrive (2.2 kW power), is versatile for pumps to machine tools. The nominal speed of 3000 revolutions per minute (actual approx. 2895 RPM under load) is a compromise for dynamic processes. The choice of the suitable kW motor is an important step.
Factors such as efficiency class (IE3 not always optimal), design, and degree of protection are relevant. This article discusses technical details, areas of use, and notes for selecting and installing your motors, especially for a three-phase motor with 2.2 kW and 3000 RPM..Technical specifications and designs
rated power, speed, and efficiency classes (IE2, IE3)
The nominal speed (e.g., 2895 RPM for a 2.2 kW motor, 2-pole, 50 Hz) takes load slip into account; the synchronous speed of 3000 RPM only applies at no load. This is an important aspect when selecting a three-phase motor 2.2 kW 3000 RPM. IE3 efficiency saves energy, but can be problematic with frequent starts. Example: AC motors FCA 90 L-2/PHE IE3 (2895 RPM).
- Power and speed: The nominal speed (e.g., 2895 RPM) deviates from the synchronous speed (3000 RPM) due to load slip.
- Efficiency classes: IE3 motors are energy-efficient, but IE2 may be advantageous with frequent starts.
- Electrical values: A 2.2 kW motor (400V) typically has about 4.3 A rated current and a power factor (cos φ) around 0.85.
- Variety of designs: Common designs such as B3, B5, B14, and combined forms (B34/B35) allow for flexible mounting.
- Shaft diameter: A shaft diameter of, e.g., 24mm is typical for size 90.
