Replacing slip ring type motors with squirrel cage motors offers enhanced productivity and additional benefits

Several conventional decade old cranes are fitted with slip ring type motors. Replacing them with squirrel cage motors offers several advantages. The most significant of them is that squirrel cage motors can be easily paired with VFD (Variable Frequency Drive). By using the VFD controller, you can experience the following advantages:

  • Smooth start and stop
  • Smooth acceleration and deceleration
  • Flexibility in setting micro speed
  • Brakes are applied at almost zero speed
  • Jerk-free transition from micro speed to full speed
  • Enhanced life of brakes and crane brake liner
  • Ease of connection with other devices universal communication protocol
