Product Description:

The model R43GENA-TS-M3-NV-02 is a part of R series Servo Motors made by Pacific Scientific for high-grade electrical and mechanical industry domains. Pacific Scientific stands as a beacon of engineering excellence by blending precision with innovation in motion control solutions. Their commitment to reliability and performance drives industries forward with unmatched expertise.

This R43GENA-TS-M3-NV-02 servo motor English type of shaft and mounting that bridges the electrical energy conversion inside the motor to mechanical work outside of it. The motor uses a G-type winding which are coils of wire that create a magnetic field when electric current flows through them by helping to produce rotational motion as torque. This R series servo motor is wrapped in a magnetic rare earth structure to generate strong magnetic fields by resulting in higher efficiency and density. The motor is found to be brakeless and aids in eliminating the need for mechanical stopping by reducing maintenance to enhance its working. Its Tachsyn feedback combines a tachometer and a synchro to provide both speed via the tachometer and position via the synchro encoder by improving motor control accuracy in industrial automation applications.

This R43GENA-TS-M3-NV-02 servo motor has a no shaft seal inside it and it consumes 2.9 amperes of rated current for proper performance. The motor’s speed of 1500 rpm is sufficient for higher torque movements and its thermal resistance of 0.72 °C per Watt means that for every watt of heat generated the temperature increases by 0.72°C. Its value of 0.011 Nm per kRPM viscous damping coefficient represents the resistance due to internal friction and air drag as the motor rotates.
