Characterization of a Direct Current Permanent Magnet (DCPM) Motor for the Modeling, Design and Control of a Non-Cots Reaction Wheel.

To determine the physical parameters of a DC motor in order to correctly obtain the model and stablish an adequate control for a self-made reaction wheel.

Year: 2016.

Description.

The parameters were:

• Armature resistance.
• Inductance**.
• Back EMF constant.
• Torque.
• Moment inertia.

** To determine the inductance, the method used was based on the time constant by charging and discharging the motor inductors.
