Part Number: DRV8307 Hi, I've designed a BLDC motor driver board with DRV8307. MOSFETs are FDS6670 and the motor is MAXON EC45 30 watt with hall sensor and encoder. I attached only hall sensors to the motor driver, not the encoder to anywhere. Arduino…
Part Number: DRV8307 I am using the DRV8307 to drive a BLDC (brushless DC) motor with 3 Hall sensors distributed at 120 degrees. The motor provides high torque at high speeds, but the torque is significantly reduced at low speeds. How can I increase the…
Part Number: DRV8307 Other Parts Discussed in Thread: MCT8316Z , DRV10970 Hi,
A dual output hall sensor is used in section 8.1.1 of the DRV8307 datasheet. I searched, but I could not find a double output (negative and positive) product in the market. Can…
Hi Annie,
Do you still require further assistance on this? Please help mark the thread as resolved if there are no further questions. Thanks.
Best Regards, Andrew
What I need is a mechanism to stop the motor without reporting an error when this happens, that is, when the Hall sensor signal is abnormal, the three-phase output is not commutated. As shown below: (0,1,2 represent three-phase output, 4,5,6 represent Hall…
Part Number: DRV8307 Other Parts Discussed in Thread: DRV8308EVM I've seen this problem previously but there wasn't an exact cause or solution given. What could cause this? Could the motor's hall sensors be misaligned from the factory? Thanx! …
Part Number: DRV8307 Dear Expert
Good day!
Our customer want to test the driver signal , so they set the test condition below:
1.Do not connect the Motor
2.Short the Rsense to GND.
3.Supply the Hall signal external ,
They found that , the faultn will …

Hi Team,
Customer would like to know if DRV8307 is not connected to the Hall signal, is there any way to test the drive waveform? Now he does not connect the Hall signal, or connects to the…
