Description

The Loche M series are an advanced compact sensored BLDC motor controller that can be used to control hall effect sensored brushless DC motors. The voltage and power output depends on the heatsink and mosfets used.

This module comes with the following controls and feedback:

  • Speed and Direction control with automatic dynamic braking
  • Tachometer Feedback (unfortunatly this is direction-less)
  • Current Feedback (voltage across shunt resistor)
  • Temperature feedback
  • Fan Control (+12V dc input pin)

Generally parts used for this motor controller to acheive a constant current of 40A @ 30V:

  • Heatsink + Fan
  • Mosfets 6 mOhm 40V @ 60A
  • Shunt 5W 0.002
