Product Description:

The 8LSA57.DA030S000-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. It delivers controlled rotary power to automated machinery such as packaging stations and gantry axes. As a synchronous design, it works with a matched drive to support accurate speed and position control during repeated motion cycles. The motor is supplied in a standard 8LSA configuration without a reinforced bearing, and the lack of a holding brake suits applications that already use external stopping methods in clean, dry environments. Length code 7 places this model in the longer frame group, allowing higher continuous torque without changing the footprint width.

The motor’s rated speed is 3000 rpm, allowing high operating speed before field weakening begins. A flange dimension of 142 mm sets the mounting interface and aligns the housing with common IEC layouts. Position feedback relies on an inductive EnDat sensor, and the electronics use EnDat version 2.2 so the drive receives absolute position data immediately at power-up. The feedback channel supports precise rotor angle detection for closed-loop speed and position control. Heat is removed by a self-cooling design with free air circulation, eliminating the need for external blowers.

Power, signals, and feedback pass through a single-cable solution terminated on a detachable connector, which reduces wiring space and keeps cable routing compact near the motor. The motor has a smooth shaft and a mounting flange, allowing direct coupling and straightforward installation on machine frames. The output end is commonly paired with clamp-style couplings rather than keyed connections. The encoder provides 19 single-turn bits and no multi-turn bits, so the feedback reports absolute position within one revolution only. Because a reinforced bearing is not specified, axial loads must stay within the published limits, and the lack of an oil seal limits use to dry zones.
