DSP technology used for BLDC speed and torque motor controller
A new speed and torque Brushless DC (BLDC) motor controller from Data Device Corporation (DDC) uses advanced Digital Signal Processing (DSP) to provide a solution that can be easily tuned for use with various motors and loads. The device’s programmability enables parameters such as speed or torque mode, number of motor poles, maximum speed, current limit, Pulse Width Modulation (PWM) frequency, and Proportional Integral Derivative (PID) control constants to be tuned during system development. This reduces the time-to-market efforts and costs, and enables the controller to be subsequently re-tuned to support multiple or evolving applications.
The PW-82535N0 has trapezoidal motor commutation and PWM switching, and can operate in either torque or nested speed/torque control modes using Hall Effect sensor feedback, that makes it useful for variable speed applications such as fans, pumps, compressors, and rotating antennas. It is a common design that can be used across multiple applications and its complementary four-quadrant drive provides reduced power dissipation, supports driving and braking in either direction, and holds torque for high-performance applications. The DDC device has a 100V, 10 amp output and a -40 °C to +100 °C operating temperature range.
