Product Description

The SF-A2.0020.030-00.050 servomotor engineered by Bosch Rexroth AG is a high performance component designed for precise motion control applications. This brushless SF servomotor with sinusoidal e.m.f. offers exceptional reliability and efficiency. It features an integrated encoder system with a choice of single turn absolute value encoder (STG) or multi turn absolute value encoder system (MTG) ensuring accurate speed and position control. Wake Industrial is a global provider of top tier industrial electronics and sells SF servo motors worldwide ensuring customers access to premium products.

Featuring a locked rotor torque of 2.0 Nm at a rated speed of 3000 min^-1 with a locked rotor current of 1.3 A. The torque constant is 1.5 Nm/A at an ambient temperature of 40°C and the motor's moment of inertia including the encoder is 3.0 10^-4 kgm². The servo motor is specially designed with a smooth shaft suitable for various applications requiring precision and high torque transmission. Furthermore, the integration of thermistors within the windings for thermal motor protection combined with a temperature range of -5°C to +155°C ensures the motor's safety and reliability under varying conditions.

The "00" in the part number indicates the motor's shaft configuration specifically mentioning a shaft with a keyway and feather key without a mating connector. This design feature facilitates positive drive torque transmission adhering to DIN 6885 standards. It's crucial to understand that under load the shaft hub connection experiences multi axis stress due to torsional, radial, axial forces and bending moments. Strong reversing operations can lead to wear at the feather key's seat altering the motor's running behavior. Therefore, for high demand applications it's recommended to opt for the basic design with a smooth shaft.
