Product Description:

The SR-L1.0008.060-14.818 synchronous servo motor is manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is intended for industrial automation axes that need accurate velocity and position control while also holding a mechanical load at standstill. An integrated power-off brake holds the shaft when drive power is removed, allowing the machine to maintain a fixed position between cycles and during emergency stops. The motor’s resolver feedback and high rated speed support use with digital drives that regulate complex motion profiles. Because the brake operates when power is removed, the axis can remain secured during short interruptions or controlled stops without relying only on drive torque.

During operation, the motor reaches a rated speed of 6000 rpm, and its torque constant of 0.73 Nm/A lets the drive relate phase current to produced torque. Position data comes from a resolver with a feedback resolution of 8192 increments per revolution, which supports fine interpolation in closed-loop control. Resolver feedback also supports continuous rotor position tracking across the motor’s operating range. The spring-applied holding brake clamps the shaft with 2.5 Nm of static torque at a supply of 24 VDC. Its 12 W coil, 0.3 kg mass, and 0.38 × 10⁻⁴ kg·m² inertia add only a small mechanical load, and the overall motor length with the brake installed is 188 mm for compact machine layouts.

When stalled, the electromagnetic circuit can withstand a locked-rotor torque of 0.8 Nm while drawing a locked-rotor current of 1.1 A, which gives a clear limit for overload monitoring. Dynamic response is influenced by a rotor inertia of 0.47 × 10⁻⁴ kg·m², which helps keep acceleration times short on light axes. Low rotor inertia also reduces the amount of stored energy that the drive must manage during frequent starts and reversals. Output power is transmitted through a keyed shaft measuring Ø11 × 23 mm, providing a standard interface for couplings, pulleys, or miniature gearheads. The shaft size supports compact mechanical connections used on pick-and-place modules, indexing tables, and light conveyor drives.
