Brushless Motor Controller

Description

Brushless motor controller with power supply between 5 and 36 VDC and max. 350 watts of power. Speed can be adjusted via the trimmer on the board or by sending a PWM signal to the dedicated input. It has 2 solder pads to select internal or external control, a jumper to select speed control via the onboard trimmer or externally, power status LED, 6-pole terminal block and 5-pole terminal block. On the 6-pole terminal block there are contacts for connecting a brake switch, a rotation reversal switch, PWM input (0-5 volts) and 5-volt power output. On the 5-pole terminal block, the 3 phases of the brushless motor and the supply voltage must be connected.

Warning!
1. There is no fuse on the board; it is recommended to add one before use.
2. Do not reverse the positive and negative power supply poles, otherwise the board will be damaged.
3. Use cables with adequate cross-section.

Technical specifications

• 5-pole terminal block connections:
  – VCC and GND: main motor power supply (connect to an external power supply)
• 6-pole terminal block connections:
  – 5V and GND: power output for external devices
  – Brake (BRAKE) and Direction (DIR)
  – Control input 0-5V PWM: for speed adjustment (if using this as PWM input, remove the jumper near the trimmer)
• On the board:
  – V/R (2 solder pads): solder together for external control, do not solder (default) for internal control
