Product Description:
The SF-A5.0460.030-14.050 is a non-contact synchronous motor that belongs from the SF series, engineered by Bosch. It operates at a rated speed of 3000 rounds/min and possess a peak speed as high as 4000 rounds/min. This motor generates a turning effect of 46.0 Nm at a locked-rotor and its torque constant is 1.580 Nm for every ampere of current usage.
The SF-A5.0460.030-14.050 motor includes a permanent magnet holding brake, that gets powered by 24 V ~10% with residual ripple of 5 % and it possess 32.0 Nm of transferrable holding torque. The brake uses 1.30 A of current and its inertia is 0.03 kgxm^2. The SF-A5 motor weighs 35 kg while the attached brake carries a weight of 3.8 kg alone. Its cylindrical shaft width is 32 mm and it is mechanically balanced. The motor provides B5 mounting through flanges and it is also applicable in terms of IM V1 and V3 mounting, where flange can be placed upward or downward, depending on the requirement. Its protection rating IP67 is met when connectors are mated and the noise level it produces is recorded below 5.8 (B) at a distance of one 3.28 ft. The SF-A5 motor gets naturally cooled by surface radiation while a ventilation fan can also be added. This motor has a moment of inertia graded as 0.0166 kgxm^2.
The SF-A5.0460.030-14.050 motor presented with a programmable absolute encoder STG and it also extends its support for an MTG encoder as well. The STG encoder calculates 8 million counts every round while MTG has a 4096 absolute revolutions per period. It comes with 1.5 size electrical terminal for power transmission and encoder wiring. The SF-A5 motor is enclosed in an aluminum body case.
Frequently Asked Questions about SF-A5.0460.030-14.050:
Q: Why does the SF-A5.0460.030-14.050 motor use a permanent magnet holding brake?
A: The permanent magnet brake ensures reliable static positioning during power failure or standby. It maintains holding torque without continuous power, reducing energy consumption.
Q: How does the STG encoder's high resolution benefit motor operation?
A: With 8 million counts per revolution, it enables precise position feedback. This is essential for applications requiring high accuracy and closed-loop control.
Q: Why is a torque constant of 1.580 Nm/A important in SF-A5.0460.030-14.050?
A: A higher torque constant means more torque is produced per unit current. This results in efficient torque control, especially in servo applications.
Q: What advantage does IM V1 and V3 mounting provide for SF-A5.0460.030-14.050?
A: These mounting styles allow flexible vertical installation options. It's beneficial when adapting the motor to different machine orientations.
Q: What are the benefits of using a 1.5 size electrical terminal on this motor?
A: It ensures secure and robust connections for both power and encoder wiring. This supports signal integrity and prevents loose connections under vibration.
