Product Description:

The R65HEAP-R2-NS-NV-00 is an R Servo motor produced by Pacific Scientific to provide accurate torque in industrial motion applications. The motor has an IP65 protection grade suitable for reliable operation in rough and high duty automation applications.

The R65HEAP-R2-NS-NV-00 servo motor has a rare earth samarium cobalt magnet system which guarantees effective high magnetic field performance. The motor has a continuous stall torque of 13 Newton meters to be stable in long operations. It has a peak torque of 45 Newton meters at dynamic load conditions. Its brushless motor construction is less maintenance intensive and has a long life span. The small rotor inertia equal to 0.00124 kilogram meter squared makes it fast and responsive to acceleration and controls. The servo motor thermal time constant can be 36 minutes which secures effective heat dissipation when operated continuously. It has a dependable holding brake of 0.262 amperes of operating current to hold the shaft position with power out. The R65HEAP-R2-NS-NV-00 servo motor weighs 18 kilograms in total providing a stable mounting and functioning. It has anti cogging technology to permit smoother rotation and the removal of low speed torque ripple. The motor housing is arranged with NEMA totality of enclosed unventilated TENV protection against external airflow.

The R65HEAP-R2-NS-NV-00 servo motor has a frameless resolver that provides accurate motion feedback required in closed loop control. It includes a viscous damping coefficient with a rating of 0.075 Newton meter per kilo revolution per minute and this aids with stable and controlled deceleration. The motor static friction is 0.26 Newton meters which adds predictable start up behavior. It runs on 24 volts DC and is designed to fit most low voltage control systems.
