• Motors

  IEC standard three-phase motors in IMB3 or IMB5 design. Protection class IP55, 400V/50Hz, thermal class F. The motors are suitable for operation with a frequency converter. The detailed information provided by the motor manufacturer for commissioning and maintenance, especially with regard to site provided motor protection devices, must be observed.
  

  Motor protection

  All motors have PTC thermistors inserted in the winding (motors with thermal contacts upon request), which automatically monitor the winding temperature of the motor. If wired correctly, they protect the motor from overload, failure of a mains phase, brake locking of the motor, and from air temperatures which are too high. The motor protection devices offered by us include the motor protection device in combination with PTC thermistors in the MSD1 K model. In general, the PTC thermistor can be connected directly to the frequency converter used.
  

  Electrical connection

  The drive motors are fitted with an outgoing cable. The electrical connection is made via a protection class IP44 terminal box which is supplied loose.
