Student on team #360, Rainier Robotics, from University of Washington.

Does anyone know what the torque is on each of the motors?

Unknown torque of motor includes:

1. Fisher-Price motor
2. Globe motor
3. Seat motor
4. Window Motor
5. Torque motor
6. Van Door motor

thanks for your information~

All the answers you need and much more are in the white papers section.

You can find speed, torque, and power measurements in this excel spreadsheet: http://www.chiefdelphi.com/papers/DrJoesMotorCalc.ZIP (2.3 megs).

You can also find two presentations done on the different motors and their uses: http://www.chiefdelphi.com/papers/FIRST_MOTORS_ETC.ppt and http://www.chiefdelphi.com/papers/motor_pres.ppt

Hopefully those links give you all the information that you need to know about the kit motors.

The more important information about the motor you want to know is how powerful those motors are, instead of just the torque because you can gear the motors so the torque you want. Basically, the more power the motor setup have, the more torque/speed it can output. Because Power = Force(N) X Velocity(m/s) and also = Torque(N-m) X Angular Velocity (Rad/sec). You can learn all these in the wonderful presentations from
Joe Johnson and Michael Ciavaglia.

Here are the power output for each motor setup from one of the presentations in the white paper section:

BOSCH Drill motor: 340w
BOSCH Drill motor with high gear: 260w
BOSCH Drill motor with low gear: 230w
Fisher Price motor: 140w
Fisher Price motor with gear box: 91w
Van door motor: 69w
Globe motor: 63w
Globe motor with gear box: 50w
Seat Motor: 31w
Window Motor: 22w
