Multispeed Motors


Two or three distinct operational speeds by pole changing
BBL manufactures multi speed motors for two or three distinct operational speeds by pole changing. These motors have a single winding for speed ratios of 1:2, for example: 1500 / 3000 rpm.

Two separate windings are used for higher speed ratios.Pole Amplitude Modulated windings can be given for 4 /6 pole motors. These are in smaller frame sizes as compared to two separate windings.
