1 Electric motor operating principles and circuits ... 3 Electric motor operating principles and circuits 6 Dahlander winding To run the machine at lower rotational speed, power supply is connected to terminals 1U, 1V and 1W. The other terminals (2U, 2V, 2W) remain un connected (Fig. 5). To use higher speed, power supply is assigned to terminals 2U, 2V and 2W. Important: Terminals 1U, 1V and 1W TWO SPEED MOTORS TWO SPEED MOTORS Two speed electric motors are usually divided into two main groups: two separate winding and dahlander winding. Two separate winding motor has many desired different polarities which offers the possibility of different speed ratios. With the dahlander winding, it is only possible to reach a pole number ratio of for example 2:4, 4:8 or 6:12. The power ratings of two speed ... Dahlander pole changing motor 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; this is achieved by altering the wiring connections inside the motor.The motor may have fixed or variable torque depending on the stator winding.

A motor could be designed for both two speeds and two voltages, but that would be more complicated and require more connection terminals. It would also be possible that some of the two speed designs may be operable at more than one voltage without adding connection options, but only operating at one speed and not necessarily at the original torque or power ratings.

Practical Machinist As motor speeds are 1:2 I would think it's a Dahlander, most likely delta double star. You should have no difficulty finding diagrams (sorry, can't post mine). Look them up in any major motor catalog. (see Jim's explanation)(I see you've found a diagram, but it doesn't show the internal motor wiring) Consequent Pole Motors:Three Speed ... electric equipment Consequent pole motors have the ability to change speed by changing the number of stator poles. There are two factors that determine the synchronous speed of an AC motor: 1. Frequency of the applied voltage 2.
