EEM 4.2-1 THREE-PHASE INDUCTION MOTOR WITH SQUIRREL-CAGE, POLE-CHANGING ACCORDING TO DAHLANDER 1KW

Thanks to its special winding, the three-phase motor with Dahlender circuit is able to operate the motor with squirrelcage rotor at two different speeds. The ratio of speeds is 2:1 for this circuit. With this motor type, simple drives can be designed with two speeds, for example, a two-staged ventilator drive.

Training contents:

• Connection, wiring and putting into operation
• Operates at high and low speed
• Use of a pole-changing switch
• Recording of the speed-torque operating response
• Operation with various load machines like e.g. ventilators, lifting equipment
