Every device is tested both statically and dynamically to insure proper operation. Encoders, resolvers and tachometers are adjusted to the correct timing, waveform shape, offset position, voltage level, etc. Every effort is made to reduce stray electrical noise to the lowest possible level, if not eliminate it completely.
Electrical parts are tested for high voltage leaks, shorts, grounds and overall physical condition. Motors are tested for vibration, current draw, back EMF, torque, temperature rise, shaft runout, keyway condition, balance, acceleration rate, magnetic field strength, magnet position and mechanical integrity, brush spring pressure, correct brush compound, etc. On low inertia motors, start/stop ramps are tested to verify acceleration capabilities.
