8LSA46.E3045D000-0 by B & R Automation

The 8LSA46.E3045D000-0 belongs to the 8LS Synchronous Motors series produced by B&R Automation. It is a three-phase synchronous motor intended for integration into industrial machinery that requires coordinated motion and accurate speed control. Within an automation cell, the motor supplies rotary torque directly to the load, making it suitable for applications where high dynamic response at the shaft is required. This type of motor is commonly used on servo axes where stable speed, repeatable acceleration, and direct coupling to the driven mechanism are important.

The front face has a flange that measures 100 mm across, allowing direct attachment to gearboxes or machine frames with matching pilot dimensions. Electrical and feedback conductors exit through an angled swivel connector, so cables can follow the machine contour without stressing the receptacle. The rotor is rated for 4500 rpm, which sets the upper continuous operating speed when the motor is paired with a compatible drive. Thermal limits are managed by self-cooling, which relies on free air circulation around the housing, so no external blower or liquid circuit is required. Length code 6 gives the motor its overall stack length and supports a balance between torque capability, installation depth, and inertia for high-cycle positioning tasks.

The motor uses standard bearings, which are suitable for radial loads typical of belt pulleys or couplings. A mounting flange supports face mounting, and torque is transmitted through a smooth shaft for backlash-free hub connections. The motor has no holding brake and no oil seal, so static load retention and contamination protection must be provided by the surrounding machine. This arrangement fits applications where external braking hardware and guarding are already part of the machine design.
