8LSA35.R0030D100-0
The 8LSA35.R0030D100-0 is a three-phase synchronous motor manufactured by B & R Automation within the 8LS Synchronous Motors series. Serving as a rotary actuator for industrial machinery, it links to a servo drive to position tables, feed systems, and pick-and-place heads. The internal 8LSA designation indicates a standard build without a reinforced bearing, and the integral mounting flange allows direct attachment to machine frames without additional adapters. This layout supports compact installation in automated stations where the motor is mounted close to the driven mechanism.
The motor delivers a rated speed of 3000 rpm, allowing direct coupling to moderate-speed loads. A flange dimension of 91.3 mm establishes the bolt pattern used in this size class. Its stator uses a three-phase synchronous winding, so torque is generated without slip and phase control remains straightforward. Rotor position is detected by a resolver, which provides analog sine-cosine signals that tolerate temperature variation and vibration. Heat is removed through self-cooling with free air circulation, eliminating auxiliary fans or liquid loops. Power and feedback exit the housing through an angled swivel connection that carries a single circular connector. A mounting flange with through holes supports installation, and length code 5 corresponds to the stack height used for the intended torque range. Connection hardware is supplied as a pre-assembled plug, which simplifies cable attachment during machine assembly.
Axis precision is specified at 10 arcmin, making the unit suitable for indexing tasks that need repeatable but not ultra-fine positioning. The shaft end ships with key to transmit torque to gears or pulleys without relying on clamping friction alone. Because there is no holding brake, static loads must be secured by external clamping or by drive torque when power is removed. An oil seal is also omitted, so contamination control must be handled by the machine enclosure. This arrangement is suited to enclosed equipment where shaft sealing and load holding are managed by other machine elements.
