Product Description:
B&R Automation manufactures the 8JSA54.EA028D100-0 as part of its 8JS Synchronous Motors series. The motor serves as a drive component in automated equipment, where it converts electrical input into controlled rotary motion. It supports positioning, indexing, and speed-regulated tasks in packaging, material handling, and assembly stations.
The mechanical envelope follows the size 5 frame code with a stator length 4, giving the motor a compact profile while maintaining usable torque for mid-range loads. Rated operation reaches 2750 rpm, so the motor can follow rapid command changes without excessive mechanical stress. Heat is removed by self-cooling, eliminating the need for external blowers or liquid cooling loops. The housing supports flange mounting, and the power and feedback conductors exit through an angled swivel connector that keeps wiring clear of adjoining modules. The shaft has a keyed end for positive engagement with a compatible coupling. The motor does not have an integrated holding brake, so an external brake or other holding method is required when a load must remain stationary without motor torque. No oil seal is fitted, and additional protection is required if the shaft may be exposed to fluids.
Motion feedback is provided by an inductive EnDat 2.1 encoder. This single-chip sensor delivers absolute position data with a maximum deviation of ±180 arcsec, supporting fine contouring through the drive controller. Its resolution is 19/0 bits, allowing discrete position steps across one mechanical revolution. The single-turn design reports absolute position within one complete shaft revolution. Self-initialization occurs automatically after power-up, allowing position information to become available without a separate initialization procedure. The inductive scanning principle tolerates vibration and magnetic stray fields commonly found near high-current busbars. A compatible B&R servo inverter can process the feedback data for deterministic position control in automated motion systems.
