Product Description:

The R43GCAA-R2-NS-VS-00 Servo Motor supports a flange mounting system and natural convection cooling. This motor delivers consistent torque output under continuous operation. It is protected by an IP rated enclosure.

The R43GCAA-R2-NS-VS-00 servo motor from Pacific Scientific offers a continuous stall torque of 3.7 Nm and operates at a continuous current of 35 Amps. It is designed for use with a maximum DC voltage of 600 Volts. The motor's back EMF constant is 128 V/KRPM and the phase to phase resistance is rated at 10.0 Ohms. The insulation is classified under Class F that allows operation up to + 155 °C. The motor features natural convection cooling and does not require forced air systems. The enclosure is rated IP65 that offers protection against dust and low pressure water jets. The flange mounting design includes four bolt holes for secure attachment to machinery. This mounting type is widely compatible with industrial automation systems. This R series servo motor includes circular MIL style electrical connectors for secure and reliable signal transmission. These connectors help ensure proper connection in rugged operating environments. The housing is constructed from black coated aluminum with heat dissipating fins that aid in maintaining thermal stability.

The R43GCAA-R2-NS-VS-00 servo motor includes a round shaft with a standard keyway for secure coupling. The shaft diameter is approximately 0.75 inches and the shaft length extends around 1.75 inches from the flange surface. The keyway provides precise mechanical alignment and prevents slippage during high torque operation. The motor’s housing is both durable and lightweight that enhances heat dissipation and ensuring mechanical reliability. The combination of thermal management, IP rated protection and strong mechanical interface makes this servo motor reliable for sustained operation in complex systems.
