8JSA42.R0015D700-0 by B & R Automation

The 8JSA42.R0015D700-0 is a synchronous motor built by B&R Automation for the 8JS Synchronous Motors series. As a drive element, it converts electrical energy into controlled mechanical rotation. It is used for positioning and speed-regulated tasks on packaging lines, material-handling axes, and other automated machinery where consistent torque and feedback-based motion control are required. This type of motor is suited to servo applications that need repeatable motion and stable response during changing load conditions.

This motor runs at a nominal speed of 1500 RPM, matching applications that favor moderate base velocities and high positional precision. Heat is removed through a self-cooling design, so no external blower or liquid circuit is needed. Rotor position is reported by a sensor with 10 angular minutes of accuracy, and the feedback device is a resolver. Mechanical attachment uses flange mounting, allowing direct coupling to gearboxes or machine frames without separate foot adapters. The motor has size 4 and length code 2, which correspond to its frame proportions and active stack length.

Cabling enters through an angled swivel connector, so conductors can be routed clear of adjacent components inside tight enclosures. Power is transferred through a keyed shaft, giving positive mechanical engagement with pulleys or couplings while helping prevent slip under load. The design is supplied without a holding brake, so static load retention must come from an external locking method or sustained drive torque. An integrated oil seal sits behind the shaft shoulder to help limit lubricant migration and reduce the entry of contaminants near the feedback components. These features support use in installations where space is limited and dependable mechanical connection is important.
