KS Reluctance Synchronous Motor

Product catalog summary

Synchronous Motor Family Overview
The KS Series motors are designed as direct replacements for similar motor types, suitable for both direct drive and geared applications. The direct drive models operate at a synchronous speed of 1800 RPM at 60 Hz. Both motor types are reversible, designed for continuous operation, and do not require maintenance lubrication. They feature a NEMA type 2-11 mounting.

Geared Models
Geared models incorporate a 'Heli-Spur' gear combination, with the primary gear stage being helical and subsequent stages being spur gears. This design ensures quiet and efficient operation. The maximum gear train loading is 250 oz-in (1765 mN-m) at 1 RPM.

Model Specifications
The document lists various models with specific details such as rated torque, output speed, input power, full load temperature rise, capacitor value, weight, maximum gear train loading, and case length. For example, the KS 2422-535 model is geared, with a rated torque of 250 oz-in (1765.4 mN-m), output speed of 1 RPM, input power of 7.5 watts, and a case length of 2.531 inches (64.294 mm).

Additional Notes
All motors are 115 Vac 60 Hz models, and a capacitor is necessary for their operation. The data provided is typical and subject to change without notification.
