You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Using variable frequency drives (VFDs) to control the speed of a compressor can provide improved occupant comfort and quieter operation in air conditioning and heat pump applications. Tight ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...

The use of permanent magnet direct current (PMDC) motors has greatly increased over the years as more products are being made portable and free to use away from mains power sockets. Generally speaking ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

Industrial applications comprise a wide variety of tasks, each with its own motor specifications. Selecting the proper motor type and how to control its operation is crucial for maximizing performance ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
