Product Description:
The Bosch Indramat's SF-A4.0172.030-04.030 code refers to a servo motor. The motor is from the SF series. It is engineered for rigorous applications that offers accurate control. This motor guarantees sustained performance in industrial settings with superior technology.
The SF-A4.0172.030-04.030 motor presents a streamlined and compact configuration, incorporating essential mechanical attributes. The dimensions of the motor flange and shaft are 142 x 24 x 50 mm. The motor is 309 mm in length. Its weight is 19 kg excluding the holding brake. Upon installation of the retaining brake the motor's maximum length extends to 356 mm and its weight escalates to 20.7 kg. The motor's moment of inertia is 40 x 10?? kgm^2 that provides exceptional responsiveness and stability. This motor has a rated voltage of 24 ~ 10% and it draws 13 A of current. The locked torque and current of the rotor are 18 Nm and 14 A at 200 rpm. The motor has a rated speed of 3000 min?. Its torque constant at 40 degrees C ambient temperature is 1.38 Nm/A that allows for fine control. The motor operates in an ambient temperature range of 0 degrees C to 40 degrees C. It also has winding overtemperature protection. The holding brake uses 0.7 A of current along with 3.1 x 10kgm^2 rotational inertia.
The Bosch SF-A4.0172.030-04.030 servo motor comes with a single-turn encoder (STG). It also offers option for the multi-turn encoder (MTG) for improved precision. The motors have an encoder precision of 20 angular seconds. The motor connectors are compatible with Bosch pre-assembled cables and provide a 6-pin connection for simple integration. Furthermore, a 17-wire encoder connector enables reliable signal transmission for precise motor operation.
Frequently Asked Questions about SF-A4.0172.030-04.030:
Q: How does the holding brake in the SF-A4.0172.030-04.030 motor enhance performance?
A: The holding brake ensures the motor stays stationary when powered off, even under load. It provides a fail-safe mechanism to maintain the position during emergencies or shutdowns.
Q: Why is the SF-A4.0172.030-04.030 motor limited to an ambient temperature range of 0 degrees C to 40 degrees C?
A: This temperature range ensures the motor operates efficiently without overheating. Above 40 degrees C, the motor might experience performance degradation, requiring derating to prevent damage.
Q: How does the moment of inertia in the SF-A4.0172.030-04.030 motor affect its performance?
A: The moment of inertia affects the motor's ability to accelerate and decelerate quickly. A lower moment allows faster speed changes, improving overall dynamic response.
Q: How does the torque constant (KT) impact the performance of the SF-A4.0172.030-04.030 motor?
A: The torque constant determines the amount of torque produced per ampere of current. A higher KT results in greater efficiency and smoother motor operation at various load conditions.
Q: What are the implications of the rated current for the holding brake in the SF-A4.0172.030-04.030 motor?
A: The rated current of 0.7 A ensures the holding brake operates without overheating. It ensures that the brake engages and holds the motor shaft securely during standstill or emergency stops.
