MD10C R3 board and RS550 motor

[font=Calibri]Hello,[/font]
[font=Calibri][/font]
[font=Calibri]I have connected MD10C R3 board ( robotshop.com/uk/cytron-13a-5-30v-single-dc-motor-controller.html ) TO[/font]
[font=Calibri]RS550 motor ( robotshop.com/uk/rs-550-motor-19300rpm-12v-6249oz-in.html ) and provided 12 V power supply to the MD10C R3 board .[/font]
[font=Calibri][/font]
[font=Calibri]Inspite of this , when I start testing the motor rotation by pressing button A, the motor seems to just vibrate and the motor A light seems to blink. If I hold the button A pressed for long duration, this behaviour continues. When I keep button B pressed, the motor seems to vibrate only once and motor B light seems to blink just once. It does not repeatedly vibrate or blink like when button A is pressed[/font]
[font=Calibri][/font]
[font=Calibri]Can you please guide me on how to get the motors working correctly ? I hope to control it from raspberry pi[/font]
[font=Calibri][/font]
[font=Calibri]I have checked the input power voltage and without the connected motor the board motor A and motor B light seems to be turn on when I press button A and button B receptively . With other DC motors ( low current ones) the MD10C seems to work fine.[/font]

[font=Calibri]Thanks[/font]

Hi,

Were you able to test the motor with another controller? If not, can you test the motor with a DC voltage? It looks like the motor may have an issue. Also, make sure the motor is properly connected.

Let us know if you are able to make the motor alone work.

Best regards,

The motor alone works fine with another controller. Its powered by DC voltage 12V. I have tested it with raspberry pi motor hat [robotshop.com/en/dc--stepper-motor-driver-hat-kit-raspberry-pi.html] under noload conditions. It has just 2 wires and by reversing polarities, the direction of spin changes

Hi,

Have you checked to see if the motor was connected properly to the controller ?

If yes, maybe the start current peak is too high and the motor controller is detecting an error. This could be possible if the Test button is not ramping up the motor control and starting it too abruptly.

Can you try moving the motor with a smooth pwm control instead of using the test buttons?

Best regards,

Thanks for your Guidance. It works now.

I used software PWM control from raspberry pi . Had to change to use higher freq (16000 Hz) in code to get it working.
