Product Description

The SF-B5.0460.020-14.015 is a brushless servo motor manufactured by Bosch Rexroth. This module is equipped with an absolute value encoder. It gives information about the speed and position of the motor. This device has a rated speed of 6000 revolutions per minute (RPM). At this speed, the device provides rated power under normal operating conditions. The value of the locked-rotor torque (M0) for this device is from  9.1 to 12 Nm. This is the peak amount of torque that this module can generate when it's starting up or if the rotor is locked. A higher locked-rotor torque can heavy loads easily.

This servo motor has a locked-rotor current (I0) of 14 to 17 A. This much current is used by the motor when it starts initially or when the rotor is locked. It is high when compared to the current drawn during normal operation. The torque constant (KT) of this device is 0.65 to 0.71 Nm/A. The torque constant relates the torque and the current flowing through the winding. This tells us how much torque is produced when the motor uses one ampere of current. A higher value indicates that the motor produces more torque for each ampere of current supplied to it.

This motor has a moment of Inertia (J) equal to 21×10-4 kgm2. This is the resistance against the changes in the rotational speed. A higher moment of inertia means it takes more torque to speed up or slow down the rotation. This servo motor has a relatively low moment of inertia. It can change its speed rapidly in response to control signals. This module uses an absolute value encoder. The rated current (IBr) is 1.33 A and the mass (mBr) is 3.8 kg. Buy with confidence, this servo motor is protected by a one-year warranty.
