Product Description

The SF-B5.0250.020-14.000, a product of Rexroth Indramat is known as a servo motor. It belongs to the SF series motors and has an IM B5 type of construction. The locked rotor torque for this motor type is 23 Nm with a rated speed of 2000 min^-1. Whereas, the locked rotor current at M₀ is 10 A in this SF series part number. The moment of inertia, incl. Encoder is 83 10^-4 kgm². It has a shaft of ∅32 x 58 mm in dimension with a torque constant of 2.3 Nm/A. The protection type of IP 67 is applied to this motor type except its output side. Also, a single-turn absolute value encoder (STG) is suitable for SF motors.

The mass with the holding brake in this motor version is 24 Kg. The motor encoder Single-turn (STG) or option Multi-turn (MTG) has +/-20 angular seconds/8 million incr./rev. This SF-B5.0250.020-14.000 servo motor has temperature control sensors with two NTC thermistors. These sensors are highly sensitive and will detect any type of temperature variation in the motor.

The transferable holding torque for this Servo product is 56 Nm with the temperature set at 120°C. A 24 +/-10 % residual ripple 5 % of supply voltage is possible with the type of SF Servo motor product. For B5 versions the rated current with holding brake is 1.33 A. The 30 10^-4 kgm² moment of inertia is also deliverable with this motor having a holding brake feature. This motor can have 3.8 Kgs of mass when holding brakes are present with it. A plug-in power connector is available in SF series motors for the encoder and output or brake. An electronic rating plate is also present in this motor system.
