Product Description:
The 8JSA72.E6020D200-0 is a synchronous motor manufactured by B & R Automation for the 8JS Synchronous Motors series. It serves as a drive element in industrial automation applications that require accurate speed and position control. The size 7 frame and length code 2 place the stator in a midrange housing that balances torque output with installation space. The motor converts three-phase electrical power into precisely regulated shaft rotation so that packaging, handling, and assembly axes can follow programmed motion profiles. Its synchronous design supports repeatable movement when paired with a compatible servo drive and motion controller.
At its rated operating point, the rotor reaches a nominal speed of 2000 rpm, supporting cycle times typical of servo-controlled conveyors and indexers. Heat is removed through a self-cooling housing, so no external blower or liquid cooling circuit is required during continuous operation. Position feedback is supplied by an optical encoder with EnDat 2.1, which provides digital communication with the drive controller. The encoder has a resolution of 13 bits for single-turn position and 0 bits for multi-turn position, allowing fine position commands and stable velocity control. For vertical axes or emergency stops, an integrated brake holds the shaft with 53 Nm of static torque, preventing the load from drifting when power is removed. The controller must track complete revolutions if the application requires position retention across multiple shaft rotations.
Power and feedback cables exit through an angled swivel connector that can be rotated to align with the intended cable route. This adjustable connection helps reduce cable strain and supports orderly routing within confined machine layouts. The motor attaches directly to machinery through flange mounting holes, eliminating the need for adapter plates and helping keep the axial assembly compact. Output torque is delivered through a smooth shaft, making the motor compatible with clamping couplings or shrink-fit hubs. Because the shaft has no keyway, the selected coupling must generate sufficient clamping force to transfer the required torque without slipping.
