WebThere is a limit on the increase of the motor torque that can be achieved by enlarging the motor diameter. Factors limiting the single disk design are: (a) force taken by bearings, (b) integrity of mechanical joint between the disk and shaft, (c) disk stiffness. A reasonable solution for larger torques are double or tripple disk motors.

WebFeb 8, 2005 · To vary the speed of an AC motor and provide constant torque throughout, you must maintain the Volts-per-Hertz ratio at a constant. So for instance, a 460V 60Hz motor must get 7.6 V/hz, derived from deviding 460 by 60. However, if you drive the motor to 100Hz, and you want the same torque at that speed, you would need to apply 760V.
