Hi, Hello to all,
First time posting here. I’ll try hard not to break anything.
I am about to purchase a set of " geared brushless motors " ( 36D Long life brushless DC geared motor, 12V 135RPM ) for a project. Product highlight mentions briefly about " Built-in " driver and the linked PDF is only two pages of very simple datasheets. I had prepared ESC modules and other components for the common brushless motors but the linked PDF completely confused me.
Could somebody help me with wiring these motors please?
For the sake of simplicity let’s say the brushless motor is in a circuit with 12V power and a PWM module with potentiometer as speed-controller.
Since this motor has integrated driver, you don’t need an ESC.
According to the schematics from PDF datasheet, you need to connect power terminals and PWM signal to control speed. You also can connect to sensor output to know the rotational speed of the motor, and there is a switch for CW/CCW rotation.
Thank you @igor_X. I’ll buy the set of motors and wire them with your suggestions. I started understanding the idea of PWM and the output sensor built into the driver of these motors. Clever and useful nevertheless. I have been trying to avoid Arduino board clutter for this build. There is absolutely no room for an Arduino Mega in the control box of this build and I was planning to complete it with a Nano or even a Micro.
This is coming from a Mech Eng. If I was not concerned with speed control or CW/CCW rotation, would just connecting the VCC+ and Ground - make this motor run at the max speed? The only reason that I am looking for a brushless DC motor is the need to run it in an inert atmosphere (Argon). If there was a need for the CW/CCW or speed control could you point me in the direction of an off the shelf PWM to do the job?
Thanks for any help you can provide.
