Brushless motors are rapidly growing in popularity because of their quieter and more reliable operation. In these motors, the controller takes care of switching around the magnetic field based on rotor position information reported using hall sensors built into the motor. Roboteq offers several controllers for brushless motors, depending on power, I/O and features requirements. The table below lists the products available.
