Multispeed motors are available in two basic versions:
• Consequent pole
• Separate winding
A separate winding motor has a winding for each speed while a consequent
pole motor has a winding for every two speeds (three speed motors have two
windings). The motor connections (and thus the types of controllers) for two
speed starters are exemplified by the schematic diagrams shown to the left.
Note that consequent pole two speed controllers involve a 5-pole and a
3-pole starter while separate winding controllers have two 3-pole starters.
Separate winding motors are usually chosen when flexibility is important,
since the speeds of a consequent pole motor are usually limited to a 2/1 ratio;
a broad range of speeds can be obtained on a separate winding motor.
Both consequent pole and separate winding motors are available in three types:
• Constant horsepower
• Constant torque
• Variable torque
Typical applications for these different types of motors are shown below.
NOTE: For detailed information involving the technical aspects of flexibility of
the starters used in the multispeed controllers, see Classes 8702, 8736 and
8810 application data.

Speed Selection
The speed of a squirrel cage motor is directly proportional to the power
supply frequency and inversely proportional to the number of poles in the
stator winding. With the frequency constant, motor speed is determined by
the number of poles.
