Product Description:

The R43HSNA-R2-NS-VS-02 brushless servomotor from Pacific Scientific encompasses a low-inertia rotor. This motor does not have demagnetization because of its high torque-to-inertia ratio. The product comprises a Viton seal around the output shaft. This device can be used in places where there is a space constraint. The unit has a square frame of size 4.25 inches. It portrays a maximum static friction of 0.03 Nm. This motor is mounted on a heatsink.

The product is free of any holding brake. This device depends on a frameless resolver for its primary feedback. The unit portrays an IP 65 protection rating. Its bearings are associated with a long lifespan because of the O ring and steel bearing insert. This motor features a high dynamic response. The product operates along with a brushless servo drive from the same manufacturer. This device produces a high torque over a wide speed range. The unit is intended to be operated only for industrial use. It offers assurance of trouble-free operation because of its brushless profile.

This motor features MS terminations. The product encompasses some special parts in its construction. The product comprises a thermistor for protection against over-temperature. This device is ideal for high-cycle rate applications. The unit can be used for washdown requirements. It has a viscous damping coefficient of 0.011 Nm/Krpm. This brushless servomotor delivers smooth operation even at a low speed. The product is noted for its high performance. The device is also characterized by high durability because of the inclusion of the Viton shaft seal. This unit can be operated in harsh environments. Its resolver depicts high accuracy and robustness that make it suitable for deployment where precision is important.
