8LSA44.R0045D200-0 by B & R Automation

The 8LSA44.R0045D200-0 is a three-phase synchronous servo motor produced by B&R Automation and offered in the 8LS Synchronous Motors series. The device is intended for direct integration into industrial automation lines where accurate speed and position control are required. By coupling to an AC inverter and feedback channel, the motor supplies repeatable torque for pick-and-place units, indexing tables, and conveyor sections, supporting coordinated multi-axis motion without mechanical gearing.

The shaft-position feedback is generated by a resolver, providing rotor angle information for closed-loop control. A flange dimension of 100 mm establishes the mounting interface and aligns the motor with gearboxes or machine frames. The housing follows length code 4, placing the stator stack in a mid-range size category suitable for moderate inertia loads. The motor includes a standard holding brake, allowing load retention when the drive is disabled or during an emergency stop. Under continuous excitation, it reaches 4500 rpm, which suits high-speed feed axes. The stated backlash tolerance is 10 arcmin, which helps limit positional play during repetitive indexing cycles.

A self-cooling design relies on free air circulation along the housing, eliminating external fans. Power and feedback leads exit through an angled connector that can swivel, reducing cable stress in confined cabinets. For rigid machine integration, the motor uses a mounting flange and a smooth shaft that mates to compression couplings without keyways, which helps minimize vibration at high speed. The assembly follows the 8LSA configuration, so standard bearings are fitted and no reinforced bearing is specified. No oil seal is installed, making the motor suitable for dry, clean environments where leakage protection is not required.
