The torque-slip characteristic form of capacitor motor
with cage-solid rotor is unacceptable (Fig.

"Companies are introducing componentry that allows the amp draw to be reduced, therefore using less energy through any type of electronic or capacitor motor
," Morrow says.
Metso says other advantages include standard 75 percent duty cycle, visual position indicators in cover, dual conduit openings for easy wiring, permanently attached cover bolts, locked rotor stall protection, thermal overload cutout, and split-phase capacitor motor
for high efficiency and long operating life.
When modeling an HVAC system using series fan-powered terminal units (FPTUs) with permanent split capacitor motors
in EnergyPlus, the user must enter values for fan total pressure rise and fan/motor efficiency.
The most common single-phase motors, the shaded pole and the permanent split capacitor motors
, tend to have worse power factors than large three-phase induction motors.
The 100 mm AC Right Angle Gearmotors are powered by these 115 V, 60 Hz single-phase TEFC permanent split capacitor motors
and offered in six standard versions with gear ratios from 5.2:1 to 50:1 and fixed output speeds from 327 rpm to 28 rpm respectively.

The company's line includes shaded pole motors, permanent split capacitor motors
, permanent magnet motors, DC motors, brush-free DC motors and generators.
Totally enclosed, permanent split capacitor motors
provide power and economy.
