Product Description

The SF-A4.0125.015-14.057 is a synchronous motor manufactured by Rexroth Bosch. The construction of the motor is of the IM B5 type. The mounting screws or bolts for the IM B5 are put through the flange's holes in the motor. A multi-axis stress situation arises at the shaft-hub connection under load as a result of bending moments, and axial, radial, or torsional forces. The feather key's seat may deteriorate due to a forceful reversing operation, changing the running action. The frame size A motor runs at 1500 revolutions per minute.

The motor follows the basic standard version. It has a holding brake but no mating connector. The mating connection supports the flow of electrical current and must be ordered separately. The brake is released using a control voltage of 24 V DC at 10%. The voltage tolerance has to be followed to release the brake safely. This synchronous servo motor's version number is 0.57. To prevent the motor from failing due to overheating, the output power drops if the motor's temperature rises above the ambient temperature range of 0 to 40 degrees Celsius.

A servo module that is connected to the windings has thermistors integrated into it for evaluation. The single-turn and multi-turn encoders are used to evaluate the rotation and overall operation of the motor. The mass of the holding brake is 0.21 kg with 2 Nm of torque at 120 degrees Celsius. Plug braking modules allow synchronous motors to be stopped immediately in the event that they cannot be actively braked due to a control failure or low operating voltage. Rexroth Bosch offers a 12 months warranty for SF-A4.0125.015-14.057.
