Product Description:

The SF-L1.0012.060-00.050 is a synchronous motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. Designed for positioning and velocity control in compact machinery, the unit converts regulated DC bus power from a matching drive into controlled mechanical rotation. Its high-speed capability and small frame make it suitable for tasks such as pick-and-place axes, labeling stations, or light conveyor zones where fast cycle execution and accurate speed tracking are required.

The motor uses a bus supply of 670 V DC and pairs directly with drive controllers that operate on a 600 V class intermediate circuit, enabling tight current control at full load. The square mounting flange measures 70 mm, providing a standardized face for IM B5 installation into gearbox adapters or machine plates. Under rated conditions, the rotor reaches 6000 rpm, giving linear actuators or spindles a wide working speed range. A torque constant of 0.64 Nm/A links stator current to produced torque, which helps with drive tuning and short-duration overload calculations. During start-up, the stator can draw a locked-rotor current of 1.9 A, a value the power stage must supply momentarily while the load is at rest.

During stalled starts, that momentary current develops a locked-rotor torque of 1.2 Nm, enough to overcome typical static friction on low-mass mechanisms. Dynamic performance is assisted by a rotor inertia of 0.000063 kg·m², allowing rapid acceleration without causing controller instability. Mechanical coupling is handled by a keyed shaft measuring Ø11 × 23 mm, while axial restraint is maintained through the IM B5 face. The housing length is 187 mm, the mass is 1.9 kg, and the motor has no holding brake. The construction withstands shocks up to 6 g, so the motor tolerates handling impacts and machine vibrations common on packaging lines.
