JYQD - V7.3E2 Brushless DC Motor Driver 12V 24V 36V 16A PWM & Analog Speed Control
- Application Notes：
- 1. Confirm the motor's voltage and power parameters do not exceed the driver board's specified range.
- 2. Compatible with 120° Hall-sensor BLDC motors. Wiring sequences may vary between manufacturers.
- Adjust Hall sensor/phase wiring sequence for optimal performance
- 3. JYQD_V7.3E2 is a bare driver board. No forced cooling required for motors under 100W, but ensure
- adequate ventilation.
- 4. The 5V output port is exclusively for connecting potentiometers/switches for speed regulation and
- direction control. External devices prohibited.
- 5. The SIGNAL port outputs motor speed pulse signals (<5mA current).

Wiring Diagram:
1. Control port
5V —Driver board internal output voltage, external potentiometer or switch for speed adjustment
and reversing operation
Z/F —Rotating direction control ports. Connect “5V” high level or no connect is Forward direction,
connect 0 V low level or connect to GND is reverse direction.
VR —Speed control port. Analog voltage linear speed regulation 0.1v -5V, The input resistance is
20K Ohm ,connect with GND when input PWM speed regulation, PWM frequency:1-20KHZ;
Duty cycle 0-100%
EL —Enable port control. Connect 5V or no connect to allow operation, connect GND to forbid
operation.
Signal— Speed pulse signal output
GND—Used for Driver board internal control
2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
P- ----DC -
P+----DC +
3:Hall sensor port
Ha--- Hall a
Hb---Hall b
Hc---Hall c
GND---GND
5V---5V output
4. Use shielded wires if the drivers board has more than 50 cm distance from the motor, otherwise it
may lead to abnormal driving, affecting the normal use.
5. Control port distance: 2.54mm,Power port distance:3.96 mm
6. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
