Product Description

This servo motor SF-A5.0250.020-00.000 is manufactured by Bosch. This module comes with a locked rotor torque of 23 Nm to start from a standstill. While, the locked-rotor current is 10 A, which the motor draws when it starts from a standstill. The rated speed of the rotor is 2000 RPM. The torque produced by this servo motor per ampere of current is 2.3Nm/A, which is called its Torque Constant (KT). The moment of inertia tells us how resistant this module is to changes in speed. This module comes with a moment of inertia of 83×10^-4 kgm².

The size of the mounting plate on the motor known as Flange Size (SW), is equal to 190 mm for this servo motor. The protruding cylindrical part from this servo motor known as the shaft, has dimensions (d x l) equal to ∅32 x 58 mm. This refers to the diameter and length of the rotating shaft. The length (L) of this module with no holding brake if equal to 300mm. To know the precise position and speed of the servo motor, sensors are used. These sensors include two encoder types which are single-turn (SGT) or mult-turn (MGT).

The encoder's precision or resolution shows us the accuracy of the encoder. The resolution of this module is 20 angular seconds per 8 million increments per revolution. The holding brake holds the motor in place when not running and in this case, its torque is equal to 56 Nm at a temperature of 120°C. The brake uses a current of 1.33 A. The moment of inertia of the brake is 30×10^-4 kgm² which tells us the resistance of this brake to changes in speed. This servo motor has a one-year warranty.
