- Choose an electric motor to a mechanical load whose torque varies in time.
- Calculate the speed, torque, power, current and voltage in different parts of an electric motor drive (consisting of mechanical load, electric motor and power supply) at constant speed and also during acceleration and braking.
- With given cooling conditions estimate the temperature of an electric motor for some time after a known load is applied.
