Product Description:
The R67HEBA-R2-NS-VS-02 is manufactured by Pacific Scientific and belongs to the R Servomotors series. Designed for use with digital drives, it provides precise torque and speed control for positioning tables, pick-and-place axes, and other motion points that require repeatable performance in industrial automation. By combining a brushless electromagnetic package with resolver feedback, the motor converts electrical commands from the drive into controlled mechanical rotation. It is suited for servo applications where accurate motion depends on low ripple, predictable feedback, and consistent response under changing load conditions.
At a continuous stall rating of 19.9 Nm, the motor can hold a static load without excessive thermal rise, while a peak capability of 48.9 Nm provides the burst torque needed for rapid acceleration. The high-speed winding supports a nominal shaft velocity of 3000 rpm, which allows fast axis travel without a gearing change. Dynamic response is aided by a rotor inertia of 1.72 kg·m² × 10⁻³, helping the drive command quick reversals with controlled current demand. The motor uses a 5.75-inch square frame with an inch-based bolt pattern, and the 7-inch stack length gives the housing a longer magnetic section without increasing the mounting footprint. The enclosure supports convection cooling during continuous duty and suits general-purpose machine layouts.
The brake circuit uses a 100 V DC holding brake that clamps the shaft during power-off or emergency-stop conditions. Contaminant ingress is limited by a Viton shaft seal, which helps protect internal bearing and feedback areas from dust or fluid exposure. Torque production benefits from samarium cobalt rare-earth magnets that maintain strong magnetic flux across a broad operating temperature range. Primary position feedback is provided by a frameless size-21 resolver in transmitter format, and no secondary feedback device is installed. The drive receives the rotor-position signal needed for commutation and speed regulation through a single feedback path, which reduces the number of internal sensing components.
