    2016-1-21 · The field (shunt) windings are made of a small diameter wire and have many turns. This means the windings have a high resistance and the current that can be drawn at startup is relatively low. Shunt wound DC motors are used in applications where the requiting torque is low but good speed regulation is important.

    The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating at an ambient temperature of 20 to 30 °C (70 to 85 °F). Therefore only the sliding frictional moment and the frictional moment of seals if applied are taken into consideration. M start = M sl M seal.
