Product Description:

The 8LSA43.E3022D100-0 motor is manufactured by B&R Automation and belongs to the 8LS Synchronous Motors series. It is a servo unit intended to drive rotary axes and positioning tables in automated machinery. In operation, the motor converts commanded electrical input into controlled rotary motion for indexing, positioning, and repeatable speed control. That behavior is useful on handling systems that need smooth starts, controlled deceleration, and consistent motion from cycle to cycle. Its compact form helps it fit equipment where surrounding components leave limited installation space.

This model follows the 8LSA standard configuration with no reinforced bearing and carries length code 3, which places it in the medium housing category. An angled swivel connection routes power and feedback lines away from the shaft, and the interface uses a field-installable connector, which helps when cable exit space is limited behind the motor. Heat is removed through self-cooling by free circulation, so no external fan is required and airflow around the housing remains unobstructed. The square flange measures 100 mm across and mates directly with gearboxes or machine frames. Rated mechanical output reaches 2200 rpm, and the motor is supplied without a holding brake. This arrangement suits axes that rely on drive-controlled stopping rather than a separate brake mechanism.

The electromagnetic package uses a three-phase synchronous design, so rotor position stays synchronized with the stator field for accurate torque production under closed-loop control. The housing supports direct bolting to machine frames and helps keep alignment stable under load. The shaft is machined with a key to transmit torque through standard keyed couplings, which supports common coupling hardware on servo-driven axes. There is no oil seal, so the front bearing area should be protected from splashed contaminants when fluids are present. This layout is better suited to installations where surrounding machine parts already limit direct exposure to liquids.
