Product Description

The Rexroth Bosch's SF-A4.0230.030-14.000 servo motor is intended for use with the Servodyn-D Inverters, which require a DC link voltage supply of 670 V. This motor differs from traditional motors because it has an advanced encoder and operates on a sinusoidal emf. The Field Control Algorithm is used to achieve sinusoidal control. A 120-degree phase shift is applied to the current. This algorithm's fundamental idea is that when the magnetic fields of the stator and rotor are at a right angle to one another, the highest torque is generated. To achieve smooth motion and maximum torque, sinusoidal current fluctuates following the rotor position.

The SF-A4.0230.030-14.000 motor is brushless and has a small A4 design or frame size. The 0230.030 motor has 22 Nm of torque (locked-rotor) that is predetermined based on its frame size and design. This servo motor's braking mechanism consists of a holding brake and an optional plugging brake. The holding brake is more suitable as the plugging brake is harsh and causes high mechanical shock that could disturb the integrated components and motor. Designs with air cooling are appropriate for operation at 1000 meters above mean sea level and in environmental temperatures between -20 and +40 degrees Celsius.

The nameplate's deviant criteria need to be followed. Every requirement listed on the nameplate must be met by the installation site. The SF motor features an aluminum frame, installation pockets for integration with compatible devices, an electronic rating plate, plug in connections for encoders, and a holding brake. The holding brake attached to the motor keeps the motor shaft at a standstill while the drive is deactivated.
