These motor also known as Permanent Split Capacitor Motor is one of the most commonly
used AC electric motors for heating and cooling units. That’s they are such key components of heaters,
ovens, blowers,fans and air cons. Most of these motors can easily be customized to meet specific motor
performance and specific airflows. The voltage ranges for these motors range from 115V up to 460V
ratedvoltage. The current motor capabilities that we produce are 80-156mm, NEMA 42 frame, 48 frames
and 56 frames PSC motors. Pioneering PSC motor designs are used in HVAC units, such as, furnace
blowers, and fan coil units.
The size of these motors ranges from 80 to 160mm. They have 1/40 to 1 horsepower and an
RPM of between 350 and 3300 depending on the size. It’s critical to consult with a technician before
choosing one for your heating and cooling unit. There are those that are single speed while others are
multi-speed. There are four types of mounting techniques for these motors. There is the Cradle, Stud,
Bracket and the Yoke. When it comes to the enclosure for the motors, there are the open ventilated, totally
enclosed or drip proof. Each of them is fitted with overload and thermal protection mechanisms.
The Uses of PSC Motors.
The Permanent Split Capacitor, or PSC Motor is one of the five types of motors in
the market used on AC systems. These include, condenser fan units, different types of direct drive fans and
blowers, condenser fans as well as heating furnace blowers. The other major users of these motors are
belted fans and blowers, double shaft fans and blowers, room air-conditioners, different sizes of
refrigeration and exhaust fans. There also lots of range/cooker hoods as well as swimming pool & spa pumps
that rely on these motors.
How PSC motors Are Designed.
A typical motor has several simple parts. They are made up of a primary
and an auxiliary winding which is connected through a capacitor that gives it a phase shift. This
phase shift ensures that the generated magnetic fields from both primary and auxiliary windings do not
cancel each other out. The capacitor is one of the most critical parts of a these motors. It’s fitted with
polypropylene to reduce the failure rate by continuing to provide current to the auxiliary windings. The
motors are also fitted with bearings and a rotor which are the only moving parts in the entire motor. The
other major bit is the circuitry.
How these Motor Work.
When powered on, the current flows through both winding and causes a phase
shift in the axillary winding because of the capacitor. The phase shift, in turn, adds up the magnetic field
which causes flow of electrons in the rotor bars in the motor providing it with a rotational motion. It’s
impossible to start the motor in the absence of the auxiliary winding because the rotor within will simply
vibrate and create a buzzing noise. That’s because the primary winding generates equal opposite direction
magnetic fields that cancel out each other ensuring zero rotational force to the rotor.
Why Choose These Motors?
You might ask yourself why it better to work with these motors rather than
its four other rivals. First, it has a simplistic design and fewer breaking points thus more reliable than any
of the alternatives. It also provide constant acceleration which is effective when it comes to units like garage
doors. It has easy systems with which you can add variable speeds. One of the reason that makes it truly
effective is that you can change the rotary motion and still maintain its torque characteristics.
