Overview
The Tork W120 timing motor is a synchronous AC motor engineered for use in Tork 8000 series repeating variable cycle time switches. Operating at 120V, 60Hz, this motor delivers consistent, self-starting performance for critical timing and control applications. The W120 is built to drive the clock mechanism in mechanical time switches, enabling precise on-off scheduling in HVAC systems, irrigation controls, electrical switching, and industrial duty-cycle applications.
Key Features
- Synchronous, self-starting motor design ensures reliable operation
- 120V AC, 60Hz operation with low 3-watt power consumption
- Heavy-duty construction rated for continuous timing control
- 60 microfarad (CAC) capacitance for stable motor performance
- Drop-in replacement for original Tork W120 timing motors
