Awesome Dahlander Motor Connection
On the other hand the connection type of υυ at the same torque of both low speeds and type of υ υυ at low torque of high speeds can be applied in the dahlander windings.
Dahlander motor connection. The dahlander motor is wound as a star motor or a delta motor with center taps on each leg of the winding. Robert dahlander a swedish engineer working for asea discovered that switching the poles in a motor led to a reduction in the speed of the motor. This is achieved by altering the wiring connections inside the motor.
