Consider a Buhler DC permanent magnet motor whose datasheet1

Consider a Buhler DC permanent magnet motor whose datasheet^1 is appended to this assignment Assume that a model 1.13.044.001 motor is connected to an ideal 12 Volt DC source. Compute: The startup current of the motor The maximum efficiency of the motor The speed of the motor when delivering 16 N-cm of torque The time required for the motor to reach its no load speed when delivering zero load torque The time required for the motor to reach operating speed when driving a load whose moment of inertia is 200 gm-cm^2
