Product Description

The SF-A5.0460.045-10.037 is a permanently excited servo motor type constructed by Rexroth Indramat. This SF series motor type works with a sinusoidal E.M.F and has a Singleturn absolute value encoder distinguishing it from the SR motor versions. The design of the frame for this servo motor type is A with a frame size of 5. Additionally, 0460 in this part number of the SF series motor reflects the locked rotor torque according to the technical data of this motor type. The locked rotor torque for this product is 46 Nm. Also, it has a rated speed of 4500 min-1 as indicated by 045 in this motor part number.

Among multiple options available for the SF series motors, this Rexroth servo motor product has a basic version smooth shaft, w/o mating connector. To determine the version of the motor, the end part of the part number should be considered. In this case, the SF-A5.0460.045-10.037 has a 037 type of version. The basic equipment for this SF motor is constructed according to the IM B5 type. As this servo motor does not come with a mating connector, it can be ordered directly from the manufacturer separately. The shaft dimensions in this motor are ∅32 x 58 mm with a Singleturn encoder. However, a multiturn encoder is available and optional for this motor type.

The precision or resolution of +/-20 angular seconds/8 million incr./rev. is also possible with this SF series motor. The noise behaviour is max.58 dB(A) at a distance of 1.0 m, IAW EN 60034-T9 for this SF servo motor type. For thermal motor protection, thermistors are integrated into the windings with evaluation in the connected servo module. Also, the temperature range for this condition is –5 °C up to +155 °C.
