Split-phase blower motors are well suited to HVAC fans and blowers, such as air conditioners, as well as tools, centrifugal pumps, clothes dryers and other appliances. With more torque for starting than shaded pole motors, and the ability to power either belt-drive or direct drive systems, this is a highly versatile fractional horsepower AC blower motor.

Frequently Asked Questions
Split-phase blower motors are single-phase electric motors that utilize a capacitor to create a rotating magnetic field. This magnetic field interacts with the motor's rotor, causing it to spin. Split-phase blower motors are commonly used in applications such as air conditioners, fans, and blowers due to their high starting torque and compact design.
Split-phase blower motors offer several advantages, including: high starting torque, compact design, reliable operation, low noise operation, and ease of maintenance. These motors are particularly well-suited for applications where high starting torque is required, such as in air conditioners and fans.
There are two main types of split-phase blower motors: capacitor-start and capacitor-run motors. Capacitor-start motors utilize a capacitor to provide additional starting torque, while capacitor-run motors use a capacitor to improve the motor's operating efficiency. Capacitor-run motors are typically more efficient and have a longer lifespan than capacitor-start motors.
When selecting a split-phase blower motor, there are several factors to consider, including: the required motor power, speed, and torque; the operating environment; and the mounting configuration. It is important to consult with a qualified professional to ensure that the selected motor meets the specific requirements of your application.
