When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

A synchronous and synchronous motors are the two main categories of ac motors. A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of ...

One operation of all motors, whether powered by ac or dc, calls for a controller. Controller manufacturers are improving features such as motor protection and brushless dc commutation. One operation ...

S-series variable-frequency AC drives feature Space Vector PWM technology (SVPWM) for improved efficiency and extended motor life. The drives have high base carrier frequencies (15kHz) for quiet ...

Increasing demands for flexibility, reliability, and ease of use, are prompting ac drive manufacturers like ABB to “come up with a number of solutions to make life simpler and cheaper for its ...

Two new AC powered STRAC drives from Applied Motion Products expand the offering to cover larger motors and applications where maximum power is required. Operating on 90 to 240 AC, the drives ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...
