Stepper motor encoding systems and methods |
摘要 |
A method of producing a smoother torque from a multi-pole motor is described. The method includes determining an angular position of a rotor of the multi-pole motor, and producing a current to drive the multi-pole motor. The current is controlled based on the angular position of the rotor so as to produce a smoother torque, without the substantially sinusoidal characteristics of torque produced by a steady current. An apparatus is described which can employ methods of the invention to provide smoother torque from a multi-pole motor.
