Some single-phase AC electric motors require a "run capacitor" to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. [5] Run capacitors are designed for continuous duty while the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are ...
Genteq is the rebranding of Regal's GE ECM, GE Capacitors and GE Commercial Motors divisions, which occurred in 2009. [ 1 ] Genteq develops and manufactures electronically commutated motors (ECM) and capacitors for residential and light commercial heating and air conditioning ( HVAC ) systems.
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
An AC motor's synchronous speed, , is the rotation rate ... The capacitor-run designs keep the second winding on when running, improving torque.
AC loads can occur in AC motor run capacitors, for voltage doubling, in snubbers, lighting ballast and for PFC for phase shifting to improve transmission network stability and efficiency, which is one of the most important applications for large power capacitors. These mostly large PP film or metallized paper capacitors are limited by the rated ...
[19] [20] [21] A capacitor-start, capacitor-run motor has two separate capacitors, one for starting the motor, and another for running it, and has a centrifugal switch to disconnect the starting capacitor, or a back-EMF relay connected in parallel with the auxiliary winding of the motor. This motor provides high starting torque and high efficiency.
