The high-accuracy TachSyn from ServoTek Products Inc. may be used as either a brushless DC tachometer or brushless DC motor commutator for monitoring the rotational speed of brushless industrial DC ...

A Coreless rotor means there’s no cogging or preferred rotor position. It has an extremely low current consumption, starting voltage and rotor inertia for extremely fast acceleration and braking. It ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between brush-type or brushless motors can complicate the selection. Even experienced designers may ...

The motor and motor control markets are thriving in a number of areas, particularly medical and robotic applications. Also, there is a rich demand for small, efficient, high- and low-torque, and high- ...

Much has been written about the process of selecting motors for applications in motion control. Motor selection can be complicated. The decisions to be made include whether to employ brushless or ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

Klaus Neuenhueskes looks at brushless DC motor control in cars and discovers that H-bridge controllers have specific advantages for designers. According to a recent report by research firm IHS, around ...
