1-9 Watt PSC Internal Capacitor Unit Bearing Motor

1-9 Watt PSC Internal Capacitor Unit Bearing Motor

Our PSC internal capacitor unit bearing motors are primarily used in commercial refrigeration applications, both evaporator and condenser, but can be used in any application demanding dependability with output ratings between 1 – 9 watts.

With over 60 years of experience our patented unit bearing motors provide our customers with years of durable, problem-free operation. Our PSC has twice the efficiency and is significantly quieter than our shaded pole motor. Utilizing a patented, internally-mounted capacitor results in a compact, single-component unit, our internal capacitor unit bearing motors provides you with direct mechanical interchangeability with our current shaded pole unit bearing motors.

  • Voltage: 115 or 230 V
  • Output: 1 – 9 watts
  • Efficiency: ~45% peak
  • Speed Range: 1300 – 1550 RPM
  • Speeds: 1
  • Rotation: CW, CCW, or reversible (determined from the lead end of the motor)
  • Type: 3.3” PSC aluminum or cast iron frame unit bearing
  • Shaft: ¼” x 20 thread is standard. Optional features include flatted end, and smooth end (5/16’ diameter shaft in cast iron frame)
  • Enclosure: Aluminum or Cast Iron (totally enclosed)
  • Bearing: Unit bearing
  • Bearing Oil: (ISO grades 15, 32, or 68) high quality paraffinic based oil selected for excellent oxidation resistance, wear protection, protection against rust and corrosion, and resistance to foaming. Also available, an oil with optimum flow characteristics at sub-sero temperatures. (ISO grades 10/15 or 68) synthetic diester-based lubricant formulated to offer extended lubrication over a wide temperature range and minimize wear.
  • Mounting: Five .150” diameter cored holes on rear (alumimum only), three #8-36 tapped through holes (cast iron only), and optional 2 side mounting bosses for pedestal mounting (both aluminum and cast iron)
