Used in various household appliances, including refrigerators, freezers, air conditioners, automatic dishwashers, and microwave ovens, as well as other products requiring a small horsepower motor, such as computer disk drives.
In 2001 the industry's products consisted of four primary product groups: fractional horsepower motors, integral horsepower motors and generators, land prime mover generator sets, and parts and supplies for motors and generators.
A fractional horsepower motor is an electric motor with output power 746 watt or less watt. Adept motors is the best manufacturer and supplier of FHP motors in pune,maharashtra and India. It offers thousands of choices the FHP motors including reversible motors with high quality. Adept motors provide wide range and best quality of FHP motors with best quality and features.

The term is 'fractional', not 'frictional'! A 'fractional kilowatt' motor is simply one with a rating below one kilowatt. In North America, the equivalent term is 'fractional horsepower', meaning 'less than one horsepower'.
I think you mean kW, not kwh. Fractional just means less than one.
A centrifugal switch is used on the starting winding of fractional HP motors. It is used to start the motor one the start winding and at a predesignated rotational speed the switch opens to de-energize the start winding and the motor carries on running on the run winding. Another device that should be on compressor motors is an unloader valve. Sometimes it is electrical driven and other times it is mechanical. It is used to used to unload the pressure from the compression cylinders. Without this pressure being unloaded the motor has to start against the pressure in the cylinder head and the added current draw on the motor is sometimes enough to trip the overload protection of the motor.
Total revenues for fractional horsepower motors in 2001 were $3.7 billion.

fractional horsepower motors represented nearly 37 percent of the industry's shipments, followed by prime mover generator sets, which accounted for 30 percent.
There are several horsepower options for 366 cubic inch General Motors engine. The largest General Motors horsepower option was 420 horsepower.

The type of motor used depends on the size of the lathe.Small "hobby" lathes use small fractional (1/8, 1/4...) horsepower ac motors which run on household single-phase power.The lathes which are used to produce crankshafts for huge marine diesel engines - or the rotor shafts of the massive alternators used to generate megawatts of electrical power - must use giant-sized motors, producing hundreds of horsepower.DC SHUNT MOTORS.Three-phase electric motor.

Fractional pitch windings are generally used in induction motors to reduce harmonics and improve the motor's performance. By using fractional pitches, the winding can achieve a more uniform distribution of the magnetic field, which minimizes cogging torque and enhances efficiency. Additionally, this design helps to reduce the size of the motor and allows for smoother operation, leading to lower noise levels and improved thermal performance. Overall, fractional pitch windings contribute to better motor characteristics and operational reliability.
Displacement does not correspond directly to horsepower rating, and the horsepower ratings of various 155cc engines (not motors) can vary greatly.
