Product Description:
The 8LSA35.DB030S200-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. The 8LSA motor is supplied in its standard configuration without reinforced bearings, which reduces mass while maintaining the stiffness required for servo operation. It is intended for closed-loop drive systems in industrial automation where accurate torque and speed control are required. The permanent-magnet rotor supports responsive motion when the motor is paired with a compatible servo drive.
The stator winding is rated for a nominal shaft speed of 3000 rpm, allowing direct coupling to gearboxes or belt stages without exceeding the speed limits of typical machine elements. A mounting flange measuring 91.3 mm across provides a reference surface for precise alignment on machine frames. Power, feedback, and brake conductors are routed through a single-cable solution, reducing cabinet wiring and eliminating the need for a separate encoder cable. Position feedback is generated by an inductive EnDat sensor that uses protocol version 2.2. The feedback system provides 19-bit single-turn and 12-bit multi-turn resolution, yielding 524,288 counts per mechanical revolution before the single-turn count wraps. Heat is removed through self-cooling and free air circulation, so an external blower is unnecessary.
A standard holding brake with static engagement secures vertical loads whenever the drive is disabled. The rotor’s electronic counter has a multi-turn capacity of 4,096 revolutions, allowing long-travel axes to retain absolute position without requiring a homing routine after each startup. Shaft torque is transmitted through the smooth shaft, which also minimizes runout when used with a properly fitted clamping coupling. The motor is revision 3 and has length code 5 for its housing configuration. It does not include an oil seal, making it suitable for clean operating areas where additional shaft sealing is not required. The standard bearing arrangement supports the radial and axial loading associated with the motor’s intended servo applications.
