Product Description

The SF-A2.0041.060-14.050 is the BOSCH series brushless servomotor with sinusoidal e.m.f with absolute value encoder STG/MTG. Brushless Servo Motors are a specific subset of BLDC motors. It is widely used for precise positioning and high speeds applications. The rated speed of this brushless servo series of motors is 6000 rpm, and the basic version with a holding brake, without a mating connector. The length of the motor is 253 mm. The protection type is IP 67, except output flange.

The locked rotor current is the critical value of the motor as it indicates the current capacity being drawn when the motor is not turning. The locked-rotor current of this brushless servo series of motors at 200 rpm is 5.6 A, whereas the locked-rotor torque at 200 rpm is 4 Nm. The supply voltage is 24 V with 10% variation acceptance and the residual ripple allowed is 5%. The admissible ambient temperature for the BOSCH SF-A2 motor is from 0 C to 40 C, and the noise behavior is max. 58 dB(A) at a distance of 1.0 m. The thermal motor temperature range is from -5 C to 155 C, and thermistors are integrated into the winding for protection. 

The torque constant of the SF-A2.0041.060-14.050 is 0.73 Nm/A, whereas the moment of inertia including the encoder is 6 x 10-4 kgm2. The moment of inertia is also known as load inertia, and it is the resistance to change in speed from the perspective of the rotational axis. The mass without holding the brake of this electrical motor is 7.1 kg. The encoder type is Single-turn (STG), option Multi-turn (MTG) with 20 angular seconds precision and 8 million increment/ revolution. The transferable holding brake is 3.2 Nm at 120 C.
