Motor Testing

In order to know how much power a motor produces, we have created a motor testing setup. Using a servo motor as a tachometer and coupling it with various motors, we can create a power curve. Using this information and mimicking the circuit, we may analyze what gear ratio and motors to use in order to minimize the effort to the user. Here is a drawing of the collar machined to mate the two motors:

By using the servo motor specifications, we will be able to identify the voltage, current and ultimately the power output, for each motor.

Output Voltage Comparison

In this test, we joined the servo motor shaft with the Mabuchi motor shaft using an aluminum collar created by the machine shop. The RPM of the servo motor is known, therefore, so is that of the tested motor. The voltage is then recorded from the sample. Using V2/R, the power is then determined.
