Two Speed Induction Motors Cr4 Discussion Thread
Dahlander motor wiring diagram. Power and control circuit for 3 phase two speed motor. Once again two phases are inter changed to reverse the motor direc tion. The power ratings of two speed winding can be very different within certain limits which are determined by the torque or power at a certain speed of the driven machine or device by the motor. This is achieved by altering the wiring connections inside the motorthe motor may have fixed or variable torque depending on the stator winding. A dahlander motor also known as a pole changing motor dual or two speed motor is a type of multispeed induction motor in which the speed of the motor is varied by altering the number of poles.
