MSK Products has a wide range of motor controllers to suit most servo control and speed control applications. We have a wide range of 3 phase brushless DC motor controllers for controlling the current loop of a servo application. Our current mode controllers (torque amplifiers) for 3 phase BLDC motors range from 55 volts to 500 volts and from 5 amps to 30 amps. These controllers will drive BLDC motors in trapezoidal mode using hall sensors for commutation. These controllers have been used in missile fin controls, antenna pointing in UAV, ground and vehicle applications, optical tracking systems and aircraft flight control surfaces.
For DC brushed motors, MSK Products also has a series of current mode controllers for torque control, ranging from 5 amps to 30 amps and 75v absolute maximum voltage. These controllers provide the same tight current control through zero torque without discontinuity as our BLDC torque amplifiers do.
For less demanding applications, MSK Products has a series of speed controllers for BLDC applications. Speed controllers can be used in areas that don’t require tight four-quadrant servo loop control. For fan and pump control, and some traction or propulsion control, MSK Products speed controllers will suffice. They consist of voltages up to 55 absolute maximum volts and currents up to 40 amps.
Package options range from hermetic to plastic encapsulated to open frame PCB assemblies for all environments. Finally, MSK Products has developed a series of digital mode controllers for torque control using analog inputs, CAN bus digital command control with field oriented control operation in both torque and speed, and sensor-less speed control for BLDC applications. These represent the cutting edge of MSK Products motor control development. Many of MSK Products motor control offerings began as custom designs, and there is the possibility of custom variations on our present motor control line.
