First post here.
Am looking for recommendations on motors for the Warman competition, at the moment, our design uses 3 DC motors.
Two of the motors will extend a set of drawer rails (2 phase hence 2 motors) using a Rack and Pinion. The arm should weigh approx 1kg. We’re assuming the use of a pinion gear that is approx 20mm in diameter, which gives us our desired RPM range of 60-80 for safety. We also wanted the motor to utilise an encoder to make sure we’re extending the arm to the right length.
The last motor will rotate a tower that will be holding the arm, the heaviest the tower will be in the end design will be 6kg, and it will be resting on a lazy susan bearing to assist with rotation. The idea was to have a roughly 30mm diameter wheel rest against the circumference of a 90mm diameter PVC pipe (tower), which will turn the tower, also using an encoder. Wanted to aim for roughly 10-15 RPM for this motor.
Not sure if this is the right place for this, but basically was just looking for recommendations.
