Application Notes:
1. Confirm the voltage and power parameters of the motor, which must not exceed the range specified by the drive board.
2. The JYQD_V8.5E is a dedicated drive board for brushless DC motors without hall sensors. However, not all three-phase
motors can be directly used with it.If the driving effect is suboptimal (e.g., startup jitter, reverse rotation, excessive current
at high speed, unstable speed, reduced efficiency, or failure to start normally under load), customers can adjust the parameters
of individual components on the drive board according to actual conditions to achieve the best driving effect.
3. The JYQD_V8.5E drive board is a bare board. For motors driven below 60W, forced cooling is not required—only normal
ventilation is needed. If the motor power exceeds 60W, forced cooling is mandatory, and a heat sink must be added (pay
attention to insulation; see the installation method below).
4. The JYQD_V8.5E drive board has no reverse polarity protection. Connecting the power supply in reverse will cause permanent
damage to the board (please pay special attention during application).
5. The 5V output port on the drive board is strictly prohibited from connecting external electrical devices. It is only suitable for
connecting potentiometers or switches on the board for speed regulation and direction change.
6. The M terminal on the JYQD_V8.5E drive board is the motor speed pulse output signal (push-pull output), with a maximum
output current of less than 5mA.
