Product Description
The robust SF-A3.0042.030-04.015 motor version is a high-performance synchronous servo motor produced by Rexroth Indramat. It is renowned for its cutting-edge features and reliability. This brushless servo motor version features a motor frame size of 3 along with a sinusoidal electromotive force. It includes a shaft with a keyway and feather key but does not contain a mating connector. It contains a holding brake. The major specifications include a torque constant of 1.6 Nm/A, along with the moment of inertia (including the encoder) of 7 (10-4 Kgm2). Also, a maximum length of 223 mm without the holding brake is also present. It incorporates a single-turn encoder, with an option for a multi-turn encoder. The precision and resolution of + 20 angular seconds and 8 million increments per revolution is offered by this motor.
This synchronous motor is capable of being braked immediately using plug braking modules if active braking is not possible due to a failure in operating voltage or control. This motor needs one plug braking module. It can be controlled by a three-phase current module. It can also be directly controlled via the inverter. The motor is uniquely designed with an inbuilt encoder, an aluminium frame that protects against contamination and corrosion, and built-in mounting pockets. It works on the back e.m.f principle and has the IP67-protected smooth shaft, critical for transmitting high torque demands.
Importantly, this motor type can handle a constant speed independent of the load. It is a great benefit in industrial operations. The smooth shaft, coupled with a holding brake that operates on the fail-safe principle, ensures secure operation when the shaft is stationary. The latest design and durable characteristics of this synchronous motor model make it suitable for diverse automation processes, enabling great efficiency.
