Product Description:
The SR-A1.0012.060-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SR Synchronous Servo Motors series. It converts drive current into controlled rotary motion for positioning axes in automated machinery where compact dimensions and high repeatability are required. Its synchronous operation supports precise speed and position control when paired with a compatible servo drive. The compact format suits indexing tables, handling equipment, packaging machines, and other automated systems with limited installation space.
This model reaches a rated speed of 6000 min−1, allowing rapid indexing while remaining within its intended operating range. The motor produces torque according to a torque constant of 0.64 Nm/A, which the drive controller uses to regulate motor current. During startup with the rotor held stationary, the motor can deliver a locked-rotor torque of 1.2 Nm while drawing a locked-rotor current of 1.9 A. These values help establish suitable current limits for the connected drive. Dynamic performance is supported by a rotor inertia of 0.63 ×10−4 kg·m², which reduces response lag during acceleration and deceleration. Position feedback is provided by a resolver with a mechanical precision of ±10 arcminutes and a resolution of 8,192 increments per revolution. The output interface is an 11 mm diameter keyed shaft with a length of 23 mm, providing positive engagement with a compatible coupling. The motor weighs 1.9 kg without a holding brake, which limits the mechanical load placed on compact gantries and moving assemblies.
The mounting flange measures 70 mm across, providing a compact interface for attachment to a machine frame or gearbox. The overall motor length without a brake is 176 mm, helping the unit fit into installations with restricted axial clearance. The bearing sets have a service life of 20,000 h under nominal radial and axial loads, supporting extended operation in repetitive servo applications. The housing tolerates shocks up to 6 g, allowing it to withstand forces associated with rapid tool changes or end-of-stroke impacts. Its brake-free configuration requires the drive or an external mechanism to retain the load whenever holding torque is needed after motor power is removed.
