Product Description:
The 8LSA75.D1030D200-3 is a three-phase synchronous motor produced by B & R Automation as part of the 8LS Synchronous Motors series. Within an automation cell, this unit operates as the primary actuator, translating drive current into precise rotary motion for pick-and-place gantries, indexing tables, or light machining spindles. Its design includes a sealed encoder interface and standardized power connections, allowing it to connect directly to B & R servo inverters while keeping overall cabinet space moderate in multi-axis machines.
The motor is built on a mounting flange that measures 190 mm across, corresponding to the A75 frame size in the series. The smooth shaft end supports backlash-free coupling, while the length code 5 stack provides additional active material for higher torque density at a rated speed of 3000 rpm. Heat is removed through a self-cooling design that relies on free air circulation, eliminating the need for external fans or liquid cooling jackets. Wiring is simplified by an angled swivel power and signal connector situated at the rear of the stator housing, so cables can be routed along the machine frame without sharp bends. The standard 8LSA configuration does not include a reinforced bearing, but it maintains the concentricity needed for suitable belt or gear loads. The absence of an oil seal reduces shaft friction and makes the motor appropriate for dry environments where additional sealing is unnecessary.
Position feedback is supplied by an optical EnDat encoder that complies with EnDat version 2.2, enabling bidirectional digital communication with the drive for parameter transfer and operating data. It provides 25-bit single-turn resolution and 12-bit multi-turn resolution, allowing absolute shaft position to be retained across as many as 4,096 revolutions. A standard holding brake maintains the shaft position when power is removed, helping prevent vertical loads from drifting while the motor is stopped. Product Revision 3 incorporates updated hardware for compatible B & R cabling kits while retaining support for applicable 8LS cable harnesses.
