Product Description:
The 8JSA54.EB050D200-0 is a synchronous servo motor produced by B & R Automation within the 8JS Synchronous Motors series. It supplies rotary motion for positioning axes, conveyor segments, and packaging machinery where high speed and accurate feedback are required. Designed for flange installation, the unit integrates directly with the manufacturer’s AC drive platforms to provide torque, velocity, and position control without additional mechanical transmission stages.
The motor’s rated operating speed reaches 5000 rpm, supporting processes that require rapid operating cycles. A holding brake generates 14.5 Nm of static torque, so loads remain fixed when power is removed. Rotor position is monitored by an inductive feedback device that offers an effective resolution of 19/12 bits S/M, with separate values for fine-position and revolution data. Internal memory tracks up to 4096 revolutions, enabling absolute positioning after power-up. Each single-turn measurement has an accuracy of ±180 arcsec, keeping cumulative position error low across the motor’s operating range. Encoder communication and power use a two-wire serial interface with the Inductive EnDat 2.1 protocol, allowing fast digital transmission and automatic parameter exchange during setup.
The compact mechanical frame has motor size 5 and motor length 4, balancing continuous torque capability with a short installation depth. The power and feedback leads exit through an angled swivel connector, making cable routing easier in confined machine spaces. Self-cooling eliminates the need for an external blower, reducing the number of auxiliary components around the motor. The multi-turn encoder retains the position reference without batteries, allowing the connected drive to identify the shaft position after a power cycle. The smooth shaft end supports rigid couplings or pulleys that use a clamping connection. Because the motor does not have an oil seal, the shaft interface should remain outside areas exposed to oil, coolant, or frequent splashing.
