SF-B4.0091.060-10.050

Product Description

The SF-B4.0091.060-10.050 is a motor manufactured by Bosch Rexroth, and belongs to the SF series of AC servo motors. This motor has a large number of applications in the textile industry, packaging machinery, industrial automation, etc. This motor exhibits the locked rotor state at a very good torque of 9.1 Nm. In this state, the motor, when applied the nominal voltage to its terminals draws a current of 14 amperes. This state is only achievable at the nominal temperature of 30 degrees centigrade of its internal windings. This motor has the capacity to provide a constant speed of 6000 min-1 which makes it quite suitable for many industrial applications. The torque constant of the motor is 0.65 Nm/A. this constant exists at the ambient temperature of 40 degrees centigrade.

This motor comes with a built-in encoder. By default, this encoder is a single-turn (STG) absolute value encoder but there is also an available option for a muti-turn (MTG) type encoder. This encoder can have a resolution of 8 million increments per revolution. The moment of inertia of this motor is 21 x10-4 Kgm2, including its encoder.

This motor's part number indicates that there is a holding brake installed in it, which can be used to stop its motion. According to its manufacturer, this brake can hold a torque of 18 Nm up to the surrounding temperature of 120 degrees centigrade. This brake works perfectly when a rated DC voltage of 24 volts is applied across its terminals. At this supply voltage, the brake consumes a current of 0.7 amperes. The brake has the capacity to absorb a very high mass moment of inertia of 3.1 x10-4 Kgm2.
