Product Description:

The R36SSNA-R2-NS-NV-07 belongs to the R Servomotors series manufactured by Pacific Scientific. This brushless unit is intended for closed-loop positioning and velocity duties in industrial automation. It tracks demanding motion profiles under drive control while maintaining a compact actuator form. That operating role makes it suitable for axes where repeatable motion, stable speed response, and accurate following performance are more important than simple constant-speed rotation.

The housing for this model is Standard, so its dimensional interfaces match the common mounting provisions used across the series and fit established machine layouts. Its rotor uses rare earth (samarium cobalt) magnets, which provide high energy density and good temperature stability for consistent torque production. For angular feedback, it employs a frameless resolver, transmitter type, size 21, and this resolver reports shaft position without optical elements, giving good resistance to dust and oil. The motor is delivered with no brake, so shaft holding torque must be supplied by the drive or an external mechanical latch when power is removed. Protective labyrinths are omitted, and the motor has no shaft seal, so the machine must keep coolant and process contaminants away from the front bearing.

The unit has no secondary feedback channel, so the control loop relies only on the primary resolver and uses simpler wiring. The Servo Motor designation indicates a current-controlled winding design that accepts sinusoidal commutation from compatible drives. Because the feedback package stays simple, the motor can be integrated where cable routing space is limited or where optical devices are undesirable. This arrangement suits indexing tables, small gantries, and pick-and-place heads that require rapid cyclic motion with minimal inertia.
