The board shown here is a breakout board for MC33035 brushless motor controller. It requires an output buffer IPM module or Mosfets to complete the closed loop brushless motor driver. MC33035 IC is the heart of the project; the project provides 6 PWM pulses as well 6 Inverse pulses outputs. On board Jumpers helps to change the Direction, Enable, Brake, and 60/120 phasing Header connector provided to connect the Hall sensors and supply, on board LED for Power and fault, P1 potentiometer helps to change the speed.
The MC33035 is a high performance second generation monolithic brushless DC motor controller containing all of the active functions required to implement a full featured open loop, three or four phase motor control system. This device consists of a rotor position decoder for proper commutation sequencing, temperature compensated reference capable of supplying sensor power, frequency programmable saw tooth oscillator, three open collector top drivers, and three high current totem pole bottom drivers ideally suited for driving power MOSFETs. Also included are protective features consisting of under voltage lockout, cycle−by−cycle current limiting with a selectable time delayed latched shutdown mode, internal thermal shutdown, and a unique fault output that can be interfaced into microprocessor controlled systems. Typical motor control functions include open loop speed, forward or reverse direction, run enable, and dynamic braking. The MC33035 is designed to operate with electrical sensor phasings of 60°/300° or 120°/240°, and can also efficiently control brush DC motors.
