Latest Patents

Gary T Brown holds a patent for "Current magnitude variation correction for open loop stepper motor driver circuit." This invention utilizes an available input to a motor controller to measure the motor power supply voltage. Typically, a scaled-down version of the voltage is sensed. The microprocessor calculates the motor control current based on this scaled-down version. A scale factor, which depends on the sensitivity of the motor current to the motor supply voltage, is also calculated by the microprocessor. The driving parameters in the controller are then adjusted to account for this scale factor. In a preferred embodiment, the driving parameters are PWM parameters. The microprocessor multiplies the measured power supply voltage to obtain a scale factor that can then be multiplied by the nominal PWM values to derive the new PWM values.
