Torque increases linearly with current, without saturation. 2-Maximum Temperature is Limited by magnet stability when testing at constant torque. All data are provided for a 25C ambient with motor mounted to a 8"x.375"x8" aluminum bracket 3. Data includes the effect of inductors connected in series with each motor phase.
