There are several different
type of fractional horsepower motors. Each type performs certain jobs better
than any other types. The characteristics of a motor designed to move air are
completely different than those of a motor used to drive a grinder, a pump, or
even a belt-driven application. Permanent-split capacitor, Shaded-pole, three
phase and Capacitor Start motors. These motors are normally used with a fan
blade or a blower wheel to move air. They are used in applications associated
with heating, air conditioning, refrigeration, ventilators, and fans. The most
commonly encountered air moving motors are Permanent-Split Capacitor and Shaded
Pole types.
Shaded Pole (SP)
FACT Used where low cost and low
power outputs are required. They have low starting torque and are inefficient.
They are used to drive blowers, bathroom ventilators, range hoods. etc....
Permanent-Split Capacitor (PSC)
FACTUsed in variety of direct-drive,
air moving applications where fairly low starting torque and high efficiencies
are required. For example, Blower motor fans.
Split Phase
FACT High starting torque motors
with the nameplate RPM identified as 1725. Suitable for belt-drive applications
such as furnace blowers, they are more efficient that Shaded-Pole motors but not
as efficient as Permanent- Split Capacitor motors.
Capacitor Start- Induction Run
FACT Highest starting torque
motors with belt-drive capability. The capacitor is usually visible and mounted
on motor frame.
Three phase
FACT The most efficient motors
produced. They are used in industrial or large commercial applications where
three-phase power is available.
Use it for replacement motors our Heating & Air Conditioning business all the time. These two motors are
universal reversible motors. They will fit most furnaces. The wiring diagrams and capacitors are included with the motors. Will
include a new capacitor which you should replace with a new motor as it may not
be the same rating as the old one with that old motor! You
can view the wiring diagrams posted on the motors below. If you need any
technical support on installing the motor feel free to email me. These motors
come with a one year warranty from date of installation. I will provide a
complete replacement motor if the motor is found defective. If you would like a quote on other motors
that are not listed here, just Email me at
[email protected].
I will need the Furnace model and serial number. I will email you a price back
within 24 hours.
