Product Description

The Rexroth Bosch company, which is specialized in producing automation components, servo drives, and control parts, is the one that designed and developed the SF-A5.0460.020-10.000 motor. To move the rotating shaft in the preferred direction, BLDC commutation techniques first locate the rotor and then use this information to produce a magnetic field. With a brushless DC motor, sinusoidal EMF is achieved by applying a specific voltage to the SF motor winding, which in turn creates a sine-wave current. This allows the motor's torque to be controlled by adjusting the sine-wave current's phase and amplitude.

The SF-A5.0460.020-10.000 motor is synchronized and features an A5 design suffix and 0460 locked rotor torque. The speed of a synchronous SF servo motor remains constant and never changes. This feature is useful for industrial drives for operations requiring frequent starts and stops and where the motor needs to run at synchronous speed despite the load torque. The starting torque of each variant of the SF series is fixed and predetermined, like this 0460.020 motor, which has 46 Nm of starting torque. The motor's starting torque needs to be high enough to initiate the movement of the motor from a standstill.

The SF series motor offers advanced cooling options like cooling by natural convection or radiation and surface cooling. The motor is equipped with integrated NTC (negative temperature coefficient) sensors, which can identify changes in the temperature of the surrounding environment and transform them into quantitative outputs. This SF motor is precisely insulated, balanced with the flanges, and has shock resistance. The SF-A5.0460.020-10.000 motor can withstand temperatures up to +155 °C.
