Product Description:

The SR-L1.0023.060-04.821 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is intended for compact, high-speed positioning axes in industrial automation, supplying rotary motion that can be accurately regulated by a drive controller. Resolver feedback is integrated so that the connected servo amplifier can close the position loop and maintain repeatable motion trajectories on packaging lines, pick-and-place modules, or similar equipment.

When operated at its rated speed of 6000 rpm, the motor provides continuous velocity with modest thermal rise, monitored by an internal thermistor with a temperature range of -5 to +155 °C. A standstill current of 3.16 Arms is required to hold load torque, while a locked-rotor torque of 2.3 Nm indicates the maximum shaft load the unit can resist without rotation during startup. The electromagnetic design delivers a torque constant of 0.69 Nm/A, allowing the drive to predict output torque from phase current. Dynamic performance is aided by a rotor inertia of 1.20×10⁻⁴ kg·m², keeping acceleration times short yet stable for midsize loads. IM B5 flange mounting is provided for rigid coupling to machinery frames, and the service life is rated at 20,000 hours under standard bearings and lubrication.

Position feedback is supplied by a resolver that produces 8192 increments per revolution of interpolated resolution and retains an accuracy of ±10 arcminutes, giving the control system fine incremental data for smooth commutation. Mechanical endurance is verified by a shock limit of 6 g, so the motor withstands transport jolts or emergency stops without internal damage. Acoustic emission does not exceed 58 dB(A), which supports installation where cabinet sound attenuation is limited. The resolver electronics and winding insulation are matched to this noise, temperature, and shock profile.
