Product Description:

B&R Automation manufactures the 8LSA45.R0022D000-0 as part of its 8LS Synchronous Motors series. The unit is a three-phase synchronous motor built for positioning and velocity tasks in automated machinery. Accurate speed regulation and closed-loop feedback keep axes synchronized with the controller. It is suited to automated equipment that depends on repeatable axis motion during continuous or indexed operation.

This motor reaches a rated speed of 2200 rpm, giving motion systems a mid-range operating point suited to conveyors, feeders, and light actuators. A flange dimension of 100 mm sets the interface size for the mounting plate and bolt pattern. Heat is removed through self-cooling by free circulation, so no external blower or coolant circuit is required. Rotor position is detected by a resolver, providing analog sine-cosine signals that remain reliable at high ambient temperatures and vibration levels. This feedback method remains useful where stable speed information is needed during continuous motion and frequent reversals. Power and feedback cables exit the housing through an angled connection, and the swivel orientation eases routing when the motor sits in confined enclosures.

A positioning accuracy of 10 arcmin supports moderately precise indexing without requiring a high-resolution encoder. The smooth shaft end is ready for clamp couplings or friction drives, which avoids keyway stress points under reversing torque. Electrical termination uses a connector interface, so cable connection is handled without hard wiring. The design is delivered without a holding brake, leaving dynamic braking to the drive or an external mechanical lock when the axis must stay fixed after power loss. Additional details include the standard 8LSA configuration without reinforced bearings and no oil seal for applications kept free of coolant spray. That arrangement suits clean installations where coolant exposure is not expected, and the length code 5 stator sets the overall body depth.
