Product Description:
The SF-B4.0230.060-14.030 is a brushless servomotor from Bosch that is equipped with an absolute position measuring system from the STG/MTG encoder series which ensures accurate feedback of its shaft angular position even after an electrical power outage and it has a stall torque rating of 22 Nm which delivers strong holding capability at standby position.
The SF-B4.0230.060-14.030 servo motor draws electric load of 25 nm when its shaft is prevented from rotating under full voltage conditions which reflects the current needed to reach that torque level at standstill position. It follows a standardized mounting style commonly referred to as IM B5, according to international electrical machinery standards (DIN IEC 34-7) which generally involves a flange mounted design without presence of feet. It is integrated with a brake system that is capable of sustaining a stationary torque load of up to 18 Newton meters, even when the internal temperature rises to 120 degrees Celsius which ensures it remains locked in position when de energized and prevents unplanned motion. It runs without traditional carbon brushes that reduces maintenance requirements and enhancing lifespan and its generated back EMF follows a sinusoidal waveform which results in smooth torque delivery and better control characteristics especially at low rotational velocities.
This SF-B4.0230.060-14.030 servo motor resistance to changes in rotational speed is 54x10kgxm^2 which factors in both the rotor and the attached encoder that suggests moderate resistance to acceleration and deceleration and it can safely operate at 6000min-1 under standard conditions which allows it to handle fast positioning tasks or high speed rotational processes. It comes in a fundamental setup that includes a built in holding brake for static load retention, but it does not ship with mating connectors for electrical hookups which means external connectors need to be sourced separately for integration.
Frequently Asked Questions about SF-B4.0230.060-14.030:
Q: How does the sinusoidal back EMF improve the performance of the SF-B4.0230.060-14.030 motor?
A: Sinusoidal back EMF enables smoother torque output and reduced torque ripple at low speeds. This results in precise motion control and better motor efficiency.
Q: Why is the IM B5 flange mounting type used in the SF-B4.0230.060-14.030 servo motor?
A: IM B5 flange mounting allows easy integration with direct-drive systems without motor feet. This reduces installation complexity and improves alignment accuracy.
Q: What advantage does the torque constant of 0.88 Nm/A offer in this Bosch servo motor?
A: The torque constant ensures predictable torque output per ampere of supplied current. This simplifies drive sizing and improves control accuracy in load-sensitive applications.
Q: How do the dual NTC sensors in the SF-B4.0230.060-14.030 help in thermal protection?
A: The dual NTC sensors monitor motor temperature at two critical points for improved thermal management. This prevents overheating and extends motor service life.
Q: How does the 54x10?? kgxm^2 inertia affect the dynamic response of this Bosch servo motor?
A: Moderate rotor inertia ensures balanced acceleration and deceleration performance. This helps prevent overshoot while maintaining stable speed control.
