111 - Starting Performance Analysis of a Universal Motor

A universal motor is a motor that rotates on both direct and alternating currents. A universal motor is used in home appliances and industrial machines because these motors are robust, compact, light, and fast with a simple construction, and have a large starting torque. However, problems such as vibration and...

106 - Iron Loss Analysis of a Brush Motor

Brush motors are used in many devices, particularly smaller-sized ones. With demands for energy-saving in recent years, higher efficiency is desired not only in high performance and large-scale motors used in HEVs and large appliances, but also in small-scale brush motors. To respond to these demands,...

95 - Analysis of a Universal Motor

Motors in electrical industrial equipment are often used for cutting and machining, so it is desirable for them to be usable at high rotation speeds. Induction motors cannot achieve high rotation speeds with commercial power supplies because their rotation speed is determined by alternating current frequency.

71 - Basic Characteristic Analysis of a Motor with 2 Brushes, 6 Poles, and 19 Slots

Small brush motors generally have a structure containing 2 poles and 3 slots, but there are times when a multi-pole structure is adopted in order to produce higher torque. The reason for this is because achieving a higher torque makes it possible to omit deceleration systems. Brush motors have a construction where...

3 - Analysis of a Permanent Magnet Brush Motor

A brush motor generates torque through the electromagnetic attraction and repulsion between its rotor and stator. They do not have many parts and do not require drive circuits, so they are widely used as a power source for compact equipment. A brush motor is composed of a magnetic circuit part,...
