Product Description:

The R24HENA-HS-NS-NV-00 belongs to the R Servomotors series manufactured by Pacific Scientific. It is a compact rotary servomotor designed to supply closed-loop torque and speed in automated pick-and-place heads, indexing tables, and other motion axes that demand consistent velocity control. By converting electrical input from a matched drive into mechanical rotation, the motor forms the primary actuator inside small-frame industrial machinery where rapid acceleration and precise positioning are required. Its compact format also suits applications with frequent starts, stops, and reversals.

This model delivers a continuous stall torque of 1.1 Nm, allowing it to hold a load without motion during standstill conditions. During short duty bursts, its peak torque climbs to 3.07 Nm, a margin that supports quick transient moves before thermal limits are reached. Rated speed is 7700 rpm, making it suitable for high-throughput cycles. The rotor inertia is only 0.021 × 10⁻³ kg·m², so acceleration times remain low and control loops can respond quickly. A round frame that measures 2.0″ OD fits space-constrained installations, and the English mounting interface matches common face-mount patterns. The standard housing style supports natural convection cooling.

Primary commutation signals are supplied by Hall sensors, and there is no secondary feedback channel, reducing cable count when a resolver or encoder is unnecessary. Stack length is 4 inches, giving the winding volume needed for the stated torque while keeping overall motor mass low. The winding is classified as High Speed, so resistance and inductance are balanced for minimal voltage drop. Magnets are constructed from rare earth (samarium cobalt), which improves thermal stability compared to ferrite designs. There is no factory-installed holding brake and no shaft seal, so the shaft must be protected from liquid ingress and any holding force must be provided externally.
