SF-A4.0091.060-04.050

Product Description

The SF-A4.0091.060-04.050 is one of the several synchronous motors in the SF series from Bosch Rexroth. The brushless servomotor has a design suffix of A and a frame size of 4. The temperature of the device can be controlled using two NTCs. The unit has N type flange precision and balance quality category. The single-turn motor comes with a smooth shaft, an electronic rating plate, and a flange on the output side. The motor comes with a one-year warranty period.

The motor operates at a speed of 6,000min^-1. The smooth shaft encompasses a keyway and a feather key. It also houses a holding brake. However, there is no mating connector. The holding brake has no backlash and features permanent magnets. The servomotor comes with an electronic rating plate and a second nameplate. The CE Certified motor operates between 0°C and 40°C. The device can be cooled by either natural convection or radiation. It has Class F insulation according to VDE 0530 specifications. The ball bearings on the flange or output side have a minimum service life of 20,000 hours. The motor comes with thermistors integrated into its windings.

The holding brake has 3.1 x 10^-4kgm² moment of inertia, 0.7A rated current and 24V +/-10% supply voltage with 5% residue ripple. The motor makes use of an absolute value single-turn encoder for providing information on the position, speed, and commutation. It has a size of 246mm and a weight of 13kg without the holding brake. The shaft has a diameter of 24mm and a length of 50mm. The holding brake utilizes the fail-safe principle for its operation and must be operated only when the shaft is not in motion. The synchronous servomotor can be dispatched to your address through our reliable delivery partners.
