Product Description:
The SF-A4.0091.060-10.015 brushless servomotor is manufactured by Bosch Rexroth Indramat. The SF motor is built so that the SF motor can reliably output torque and keep the speed stable. The motor works with automation and motion control systems that need accurate and regular feedback.
The SF-A4.0091.060-10.015 brushless servomotor has a maximum speed of 6000 min⁻1. It has a locked-rotor torque of 9.1 Nm, which makes it possible to generate power efficiently. It needs a 14 A locked-rotor current that allows for safe startup under load. Its value is 0.65 Nm/A, which makes the torque output match the current input. The motor has a moment of inertia of 21 × 10⁻ kg·m², which keeps it stable when the load changes. The flange is 142 mm wide, which means it can still be used with normal mounting assemblies. The shaft is Ø24 ×50 mm in size, which allows for a smooth transfer of power. The motor length of the SF-A4.0091.060-10.015 is 246 mm without the holding brake, and it weighs 13 kg, which helps make tools lighter. The encoder is an SF type, and it has a single-turn STG and an alternative multi-turn MTG. It has a resolution of ±20 angular seconds and 8 million steps per turn, which makes motion more accurate.
At 50 ± 0.5 mm from the flange to the shaft end, the axial alignment is very accurate. The flange is 142 mm wide and 177 mm tall, which makes it a good fit for normal equipment profiles. The mounting pitch is Ø165 ± 0.1 mm, which makes sure that the fitting is safe. The center hole is shaped like M8 DIN 332-DS, which allows for common ways to connect. If the flange precision meets DIN 42 955 standards, the interface shape will be the same.
Frequently Asked Questions about SF-A4.0091.060-10.015:
Q: How does SF-A4.0091.060-10.015 ensure motion accuracy?
A: It uses an SF absolute encoder with ±20 angular seconds precision. This enhances position control in closed-loop motion systems.
Q: Why is SF-A4.0091.060-10.015 torque constant 0.65 Nm/A?
A: The 0.65 Nm/A constant balances torque generation with current input. This supports efficient performance during dynamic load changes.
Q: How does SF-A4.0091.060-10.015 minimize the inertia impact?
A: The moment of inertia is 21 × 10⁻⁴ kg·m². It reduces oscillations and improves dynamic system stability.
Q: Do SF-A4.0091.060-10.015 dimensions meet flange standards?
A: Yes, it follows DIN 42 955 flange precision. This ensures reliable fitment across standard equipment assemblies.
Q: Does SF-A4.0091.060-10.015 allow a multi-turn encoder?
A: Yes, it supports an optional multi-turn MTG encoder. It enables extended position tracking in multi-revolution applications.
