The motor can also be run up to the high speeds required for the spin cycle. [5] However, universal motors are usually relatively inefficient: around 30% for smaller motors and up to 70–75% for larger ones. universal IP23. Such a motor would need a large fan to circulate enough air, decreasing efficiency since the motor must use more energy to cool itself. Another negative aspect is that these motors may only be used where mostly-clean air is present at all times. This version of Internet Explorer is either no longer supported by Microsoft , or is obsolete and some features of our store may no longer be supported. Various schemes of embedded resistance, inductance and antiphase cross-coupling were attempted to reduce this. [3], An advantage of the universal motor is that AC supplies may be used on motors which have some characteristics more common in DC motors, specifically high starting torque and very compact design if high running speeds are used.[3]. In some smaller applications, a fan blade attached to the shaft often acts as an artificial load to limit the motor speed to a safe level, as well as a means to circulate cooling airflow over the armature and field windings.
