How to optimize your conveyor technology with the right drive solutions – including a checklist!
Why are frequency inverter compatible motors so important for modern conveyor systems?
Modern conveyor systems must be flexible and efficient to respond to dynamic production requirements. Frequency inverter compatible motors enable precise speed and torque control, which can lead to optimized processes, reduced mechanical wear, and an increase in throughput, for example in sorting systems, by up to 20%.
What are the main advantages of using frequency inverters in conveyor systems?
The use of frequency inverters offers significant advantages: noticeable energy cost reductions of up to 30% through demand-driven speed control, reduction of mechanical wear through soft start and soft stop, which can extend the service life of the system by up to 15%, and an optimization of material flow through precise control options.
What should I pay attention to when selecting a motor for operation with a frequency inverter?
Several factors are critical in the selection: the motor design (asynchronous or synchronous motor),the compatibility of voltage and frequency, a robust insulation system to protect against voltage surges, an effective thermal management especially at low speeds, and the EMC compatibility.The specific load characteristic and environmental conditions of the conveyor system must also be considered to find the suitable frequency inverter compatible motor for your conveyor system .
What are the differences between U/f control and vector control in frequency inverters?
Die U/f control is a simple and robust control method, which is well-suited for standard applications in conveyor systems. The vector control (with or without encoder), on the other hand, offers more precise control of torque and speed. It is preferred for demanding tasks such as positioning or synchronization and allows for the full potential of a frequency inverter suitable drive for conveyor systems to be utilized. Sensorless vector control can also reduce system costs.
What advantages do decentralized frequency inverters offer for conveyor systems?
Decentralized frequency inverters, mounted directly on or near the motor, significantly reduce wiring effort and save valuable space in the control cabinet. This simplifies commissioning and maintenance and can reduce installation times by up to 30%. They support modular plant concepts and often have integrated PLC functions for autonomous control tasks.
How do frequency inverters contribute to energy efficiency and safety in conveyor systems?
Frequency inverters increase energy efficiency by adjusting the motor speed to actual demand. Regenerative frequency inverters can feed braking energy back into the grid, which can reduce overall energy consumption by up to 25%. Integrated safety functions such as STO (Safe Torque Off) and SS1 (Safe Stop 1) enhance machine safety directly in the drive, often making external safety relays unnecessary, thus reducing system complexity and costs.
Can standard motors be operated with frequency inverters, or are special motors required?
Many modern frequency inverters are designed to be easily operated with standard asynchronous motors. However, it is important to pay attention to a suitable insulation system of the motor to withstand voltage spikes. For maximum efficiency and dynamics, or in the case of certain synchronous motor technologies, specialized motor designs may be advantageous. Coordination between motor and frequency inverter is always recommended.

What is a frequency inverter and how does it work?
A frequency inverter changes the frequency and voltage of the motor power supply for speed control. This principle of speed control through frequency change is fundamental for energy efficiency and process optimization, especially when motors for frequency inverter operation are used in conveyor technology.

Principle of speed control through frequency change.
The speed of an asynchronous motor is proportional to the frequency of the supplied current. If the frequency inverter changes this frequency, the motor speed changes. This method allows for continuous speed adjustment of conveyor belts or roller conveyors.

Precise control optimizes material flow.Selection criteria for frequency inverter compatible motors.
Motor types and their suitability for frequency inverter operation.
The suitability of motors for frequency inverter operation varies. Asynchronous motors are robust; synchronous motors often offer higher efficiency. The choice of motor type depends on specific conveyor system requirements, such as load profile and dynamics, when selecting a suitable motor for frequency inverter operation in conveyor systems. In intralogistics, IE4 synchronous motors can save operating costs by over 10% compared to IE2 asynchronous motors. In der Intralogistik können IE4-Synchronmotoren Betriebskosten über 10% gegenüber IE2-Asynchronmotoren einsparen.
Technical specifications and requirements.
Voltage compatibility and a robust insulation system (e.g. IEC TS 60034-25) are important technical details. Effective thermal management through optimized fans or external ventilation avoids overheating at low speeds, an important aspect for any inverter-safe motor for conveyor systems.. EMC compatibility, through integrated filters or special motor cables, minimizes interference. A controllable geared motor with an integrated frequency inverter can be advantageous.
Adjustment of the motor to the specific conveyor application.
Requirements vary depending on the application (e.g. bulk goods, sensitive components). Knowledge of the load characteristic (constant/variable torque) is fundamental for the design of the drive system, especially for a motor designed for variable speeds in conveyor systems using frequency converters . Incline conveyors often require motors with high starting torque and holding brakes. Environmental conditions must be considered: dusty environments require IP65+, the food industry often stainless steel designs or hygienic design.Integration and operation of frequency converters in conveyor systems
