A small permanent magnet motor has a torque constant kT=0.1 Nm/A and a back e. m.f. constant ke=2.50 V/krpm. The total internal resistance is R=10 Ω. Determine the torque for maximum power and the maximum rotational speed if the applied voltage is V=5V. Sketch the characteristic curves of a generic permanent magnet motor.
