Remote Control Lawn Mower Build Pt.2 Motor Brake Removal






This video shows how to remove the electric brake on the wheelchair motors. so they will operate with 12V.

This chair came in on Friday the 28th of January 2011, it was not a runner, bad paint work, and in need of a total rebuild. Firstly the chair was stripped to...

    I am building a robot with wheelchair motors, and that coil is only a few hundred milliamps (maybe 250mA to 500mA) which is about 1/2 amp. It doesnt take much to disengage it. For a robot, there is no reason to have them on anyway unless you want to have the wheels lock in place when stopped.

    Where did you find one of those expensive ass wheelchairs from anyway to where you could take it apart. Of like to get one. I would like to try and build one myself. Baddest mower on the block

    I think you should keep it 24v so the motors can run at the proper speed. Make it 12v cuts the amperage and the horsepower in half. It will be slower. The brakes weren't the reason it was 24v. I'm certain the brakes required less voltage then that and were cut down by a resistor.

    I just removed the disk pad section (The three srews on the perimeter and the center screw). The brake will then be disabled and I left the coil section with the white wires for I saw no need to remove it although you could if you want. The motor then ran on 12 or 24 volts. Of course it ran slower on 12v but the brake was diabled. If anyone sees a problem with this please let me know.

    Another way to brake the motor is to apply positive voltage to both leads at same time. This could be just temporary to stop the mower.
