Information
In the asynchronous motor, the rotor does not run synchronously (but asynchronously) to the stator rotating field. The deviation depends on the load (torque). It is close to zero at zero load and greatest at breakdown torque. This feature makes it possible for asynchronous motors to start directly on the power supply (without an inverter). The exception is specially developed and optimized asynchronous motors for inverter operation. Asynchronous motors are available in a very wide range of designs. From standardized IEC versions as shown on the left, which have special features such as brake motors, with explosion protection, with forced cooling, different numbers of poles, to high-tech versions for advanced control tasks as shown in the picture below.
For more information, please refer to the special pages on the individual motor technologies.
An asynchronous motor, optimized for vector-controlled inverter operation and forced cooling, which ensures that the motor is cooled sufficiently even at low speeds and thus cannot overheat.
