Item # 111919, Leeson Single Phase PSC Type Resilient Base TEAO Fan & Blower Motors

|
1/2 HP, 825 RPM, NEMA Frame 56HZ, 115/230 V- Single Phase
- PSC Type
- Resilient Base Totally Enclosed Air Over (TEAO)
Two-Winding Variable Torque PSC Type for Shaft Mounted Fan Applications
These fan and blower duty motors are designed for dependable, energy saving performance in applications where the fan is mounted on the shaft of the motor. The permanent split capacitor design does not require a centrifugal switch, resulting in higher reliability than on other types of single phase motors. This design is also more energy efficient and less expensive to operate.
These motors may be operated at listed speed or two speed operation may be achieved by using the proper auxiliary switch. They are suitable for variable speed by adjusting the voltage to the motor using a variable voltage control.
Overload protected with a UL and CSA recognized automatic reset protector. Grounding provisions. Totally enclosed, dust tight design, with resilient mounting for quiet operation. Lubricated with Exxon POLYREX® EM high temperature lubricant. Exterior coating on 56- frame motors is two-stage epoxy and on 48-frame motors a baked-on powder coat is applied for extra corrosion resistance in tough applications. Because of the inherently low starting torques of this design, these motors are not suitable for belt driven fan applications. They must be mounted within the air stream of the driven fan.
