Dahlander Motors - Siemens

 Dahlander Motor - Siemens

  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. It is named after its inventor Robert Dahlander (1870–1935)

Application

Pumps, wherein two speeds can be used to control the output flow
Fans, to get variable air flow output
Crushers
Milling applications
Cranes, where two speeds can be used in hoisting applications: one speed for material movement and the other for positioning the material held in the hoist
