A system is provided for controlling rotation of a rotor relative to a stator of a stepping motor, linear motor, or the like. A driver pulse generating electronic device outputs driver pulses to a driver of the motor for causing discrete steps of rotation or linear movement of the rotor relative to the stator to control rotation or linear movement, direction of rotation or linear movement, and speed of rotation or linear movement of the rotor relative to the stator. The driver pulse generating electronic device is configured such that a signal proportional to a difference between a command input signal provided by a controller and an encoder signal of actual rotor position of the motor is used to determine when a next driver pulse is output from the driver pulse generating electronic device. A method is also disclosed.
A control system for a motor having a rotor and stator, comprising a driver pulse generating electronic device for outputting driver pulses to a driver of the motor for causing discrete steps of rotation or linear movement of the rotor relative to the stator to control rotation or linear movement, direction of rotation or linear movement, and speed of rotation or linear movement of the rotor relative to the stator, the driver pulse generating electronic device being configured such that a signal proportional to a difference between a command input signal provided by a controller and an encoder signal of actual rotor position of the motor is used to determine when a next driver pulse is output from the driver pulse generating electronic device.
A method for controlling rotation or linear movement of a rotor of a motor relative a stator of the motor, comprising the steps of generating driver pulses with a driver pulse generating electronic device and outputting the driver pulses to a driver of the motor for causing discrete steps of rotation or linear movement of the rotor relative to the stator to control rotation or linear movement, direction of rotation or linear movement, and speed of rotation or linear movement of the rotor relative to the stator, wherein a signal proportional to a difference between a command input signal provided by a controller and an encoder signal of actual rotor position of the motor is received and used by the driver pulse generating device to determine when a next driver pulse is to be output.
