A special type of brushless motor is called a limited-angle torquer (LAT).

Experts say the single most important advance in PM motor technology was the introduction of rare-earth magnetic materials in the mid-1970s.

Generally, nonrotating wire contacts on screw-terminated connectors handle 12 through 30 awg solid or stranded wire.

Stepping motors offer many advantages.

Transistors are three-terminal semiconductor devices.

Not long ago, the only accelerometers available employed either a quartz crystal or moving coil.

Three major components in any fiber-optic system are the transmitter, receiver, and fiber cable.

Some types of sensors actuate an integral switch in response to a stimulus of some kind.

The days of matching catalog motors with available power supplies and controllers may be over.

There are no standards for constructing power supplies, but common forms are produced by many manufacturers.

One operation of all motors, whether powered by ac or dc, calls for a controller.

Air movers can be generally classified as fans or blowers.

The most common type of power supply today is the switching supply.

Power control is provided by high-power devices and their drive circuits.

Connectors are divided into four categories based on operating environments: commercial, industrial, military, and hermetic.
