B&R 8LSA35.DB030S100-3 3000 RPM 2.1 Nm Multi-Turn Key Shaft Servo Motor

The B&R 8LSA35.DB030S100-3 is a 3000 rpm synchronous servo motor designed for machine axes that need stable torque delivery, repeatable positioning and retained position information across multiple shaft revolutions. Its 2.10 Nm nominal torque rating makes it suitable for compact industrial mechanisms that operate at moderate speed but require reliable motion control throughout frequent production cycles.

This configuration uses an EQI 1331 FS multi-turn encoder with EnDat 2.2 communication. Compared with a single-turn feedback version, the multi-turn encoder can support applications where the controller needs to track the mechanical position over more than one revolution. This is useful for rotary mechanisms, material feed systems, positioning modules and machinery that must recover a known axis position after controlled shutdown or restart procedures.

The 14 mm keyed shaft provides a positive mechanical interface for timing-belt pulleys, sprockets, gears and keyed couplings. It is suitable for transmission-driven equipment where the shaft connection must remain secure during repetitive acceleration, deceleration and direction changes. The motor does not include a holding brake, so it is generally intended for horizontal axes, rotary units or machine structures with separate load-retention arrangements.

Its single-cable connection design helps reduce wiring complexity between the servo motor and drive. The angled swivel connector also supports more practical cable routing in compact equipment layouts. The B&R 8LSA35.DB030S100-3 is suitable for replacement and retrofit projects when the original application requires the same multi-turn encoder type, keyed shaft configuration, mounting dimensions and compatible servo drive settings.
