Product Description

The SF-B5.0250.020-10.015 manufactured by Rexroth Indramat is a servo motor belonging to the SF series motors. It features a rated speed of 2000 min^-1 along with a locked rotor torque of 23 Nm. Also, the locked rotor current for this part number is 10 A when at M₀. However, the moment of inertia when holding the brake is present is 30 10^-4 kgm². The precision or resolution by its encoder type is 20 angular seconds/8 million incr./rev. Additionally, improper assembly of encoder and power connection cables can cause this servo motor type to run inadmissibly at high speeds and can destroy them. It’s essential to utilize pre-assembled cables and also check self-made power connection cables and encoders before commissioning.

This synchronous motor version can be braked immediately by using plug braking modules if the servo motor is unable to be braked actively because of the operating voltage or control failure. Note that one plug braking module can be used for this motor type. You can control this plug braking module through the three-phase current module. Also, it can be directly controlled by the inverter. To activate this plug braking module in the motor, it is pivotal to first remove the toque from the motor.

The SF-B5.0250.020-10.015 has a torque constant of 2.3 Nm/A and shaft dimensions of ∅32 x 58 mm. The rated plug braking resistors are used to ensure that this motor is halted at its maximum current within the shortest period. This rating depends on the rotational energy and the external moment of inertia. The moment of inertia, incl the encoder for this servo motor, is 83 10^-4 kgm². The motor connector for this version contains 6 pins.
