Permanent-magnet synchronous motors, rotating
Permanent-magnet synchronous motors with or without encoder are supported.
The following encoder types are supported:
● Encoder with position information (e.g. without CD track or reference signal)
● Encoder without position information
For operation without encoders or with encoders without position information, a pole position
identification must be carried out (see Section Pole position identification for further details).
Typical applications include direct drives with torque motors, which are characterized by high
torque at low speeds. When these drives are used, gear units and mechanical parts subject
to wear can be dispensed with if the application allows this.
Temperature protection can be implemented using a temperature sensor (KTY/PTC). In
order to achieve a high torque accuracy, we recommend that a KTY temperature sensor is
used.
