Features of VECTOMOTOR VM600M asynchronous motors

Asynchronous motors – Induction motor (IM)

The reliability and great robustness of asynchronous motors make them some of the most important and frequently used drive technologies. They function motorically as well as regeneratively. The name “asynchronous motor” comes from the fact that the rotor of asynchronous motors does not run synchronously but asynchronously to a ro-tating magnetic field.

Advantages of asynchronous motors

•    Easier to maintain than motors with magnets
•    Less expensive to purchase
•    Higher efficiency in partial-load operation
•    Suitable for high rotational speeds, which allows high outputs to be achieved in combination with VECTOPOWER inverters

Asynchronous motors: Further information

The reliability and great robustness of asynchronous motors make them some of the most important and frequently used drive technologies. They function motorically as well as regeneratively. The name “asynchronous motor” comes from the fact that the rotor of asynchronous motors does not run synchronously but asynchronously to a ro-tating magnetic field.

Structure and function of an asynchronous motor

Unlike PM motors, for example, asynchronous motors do not have any magnets. In the housing of an asynchronous motor, the motor phases are connected to coils that gener-ate a magnetic field. With asynchronous motors, the flow of current in the rotor is trig-gered via a voltage induced by the rotational field. The voltage is only induced at the rotor in the moment when the applied magnetic field passes the rotor. Since the mag-netic field of the rotor is only generated by the magnetic field of the stator, the rotor magnetic field basically runs asynchronously to the stator magnetic field, in other words with a time delay. This delay between the two magnetic fields is called “slip”.

Asynchronous motors from ARADEX

In developing the VM600M product line of asynchronous motors, ARADEX has succeed-ed in almost completely eliminating two disadvantages that asynchronous motors often have: First, the size and thus the required installation space could be reduced. The sec-ond weakness of asynchronous motors is that they are normally somewhat less efficient at the rated operating point. When ARADEX asynchronous motors are used in combina-tion with VECTOPOWER inverters, however, it is possible to compensate for the typically weak torque of asynchronous motors when starting on a hill.
ARADEX asynchronous motors for traction drives are designed for direct drive, which means that they can be mounted directly on the cardan shaft without an additional gearbox. The motors are optimized for use in partial-load operation, which makes them particularly suitable for vehicles that are used in urban traffic, for example, buses, deliv-ery vehicles, or garbage trucks, allowing a high overall efficiency in these applications.
Combination with the VECTOPOWER inverters makes it possible to realize extremely efficient drive solutions that allow very high torques, especially when starting from a standstill.
