Japan Servo Co - KS7P8-11 - P/N 6813649 – AC Synchronous Motor, 25VAC, 250/300 RPM.

Japan Servo Co - KS7P8-11 - P/N 6813649 – AC Synchronous Motor, 25VAC, 250/300 RPM. A synchronous motor is an AC electric motor that rotates at a constant speed, known as synchronous speed, which is locked to the frequency of the AC power supply. It achieves this by using an electromagnet in the stator to create a rotating magnetic field, which is then synchronized with the magnetic field of the rotor, allowing the rotor to turn at the exact same rate. Unlike induction motors, synchronous motors maintain this speed from no load to full load, and their speed is not affected by the load. Type: KS7P8-11, Part No: 681364, EC No.: 344744 Status: Discontinued Synchronous 25VAC 50/60Hz Speed: 250/300RPM. Requires 20uF capacitor (Included). On a 2.78" Square Plate with 4 mounting holes 2.2" apart. Shaft: 1/4" Shaft x 0.6" long and has a gear 0.49" Diameter. Motor is 1.6" behind plate. Maybe replaced with P/N 6813649. Applications: These characteristics make it suitable for applications requiring precise, consistent, and low-speed rotational control such as Timing Devises, Automation Instruments, Display Equipment and Turntables, HVAC Systems, and Small Machinery.
