Induction three-phase electric motors with increased slip

Асинхронные с повышенным скольжениемAiRS.jpg

The motors are designed for drive of mechanisms with high time lag as well as mechanisms, which operate in repeatedly short-time mode (S3). These motors have slip, in case of nominal load, higher than basic motors. Critical slip of these motors is about 40%. It is provided by increasing of rotor winding resistance. The motors are unified with the basic version: the motor have additional letter “S” after series name. The motors are designed to operate with three-phase AC.

  • Network frequency – 50 and 60 Hz
  • Voltage – 220-660 V
  • Protection degree of motor – IP54 (can be manufactured with IP55 on customer’s request)
  • Protection degree of current lead – IP55
  • Insulation class – F.

Technical characteristics in case of 380 V, frequency of 50 Hz
