Product Description:
The 8LSA37.R2045D300-3 is a servo motor manufactured by B & R Automation for the 8LS Synchronous Motors series. It belongs to the 8LSA configuration and is supplied in a standard build without reinforced bearings. The motor is product revision 3. Designed for industrial automation, this servo actuator drives indexing tables, packaging axes, and material-handling gantries that require precise rotational control. Its synchronous design supports controlled acceleration, deceleration, and positioning when paired with a compatible servo drive.
The motor reaches a rated speed of 4500 rpm, allowing fast cycle times on high-throughput machines. A flange dimension of 91.3 mm provides the mechanical interface for gearboxes or direct-drive frames. Heat dissipates through a self-cooling design that uses free air circulation and does not require forced ventilation. For controlled stops and power-off holding duties, a standard holding brake is integrated behind the rotor. Shaft position is reported by a resolver, which supplies analog sine-cosine feedback that remains reliable in electrically noisy environments. This feedback allows the connected drive to monitor rotor position throughout the motor’s operating range.
Power and feedback lines use an angled connection with a swivel connector that supports flexible cable routing around the motor housing. The connection hardware is a keyed circular connector intended for industrial cabling. The drive chain maintains positional repeatability within 6 arcmin, making it suitable for pick-and-place or labeling stations that require tight accuracy. Torque is transmitted through a shaft end equipped with a key, providing positive engagement with couplings or pulleys. The motor uses a three-piece stator with a three-phase synchronous winding. Its length code 7 corresponds to the active stack height and the resulting motor proportions. The shaft is supplied without an oil seal, making the motor suitable for dry environments where protection against lubricant migration is unnecessary.
