EEM 3.3-1 Single-phase induction motor with bifilar starting winding 1kW

Single-phase motors with bifilar starter winding are asynchronous (induction) machines. Besides a primary winding, they have a starter winding with high internal resistance, which is partially bifilar designed and thus magnetically ineffective. It is disabled after start-up. The motors do not contain any parts which are subject to wear and tear such as collectors or slip-rings and operate with fixed, almost synchronous speed. The power range can reach up to around 2 kW.

Training contents:

• Connection, wiring and putting into operation
• Reversing rotation direction
• Recording of the speed-torque operating response
• Operation with various load machines such as ventilators
