Product Description:

B & R Automation manufactures the 8JSA32.R0030D300-0 as part of the 8JS Synchronous Motors series. This synchronous motor converts electrical power into controlled mechanical rotation for pick-and-place arms, indexing tables, and material-handling spindles that must follow commanded motion profiles with repeatable accuracy. Its compact form helps it fit machines with limited axis spacing, while servo-oriented construction supports stable closed-loop operation during frequent starts, stops, and direction changes.

The motor reaches a nominal speed of 3000 RPM, allowing direct coupling to gear stages or belt drives that expect high-speed input. Internal heat is removed through self-cooling, so no external blower or liquid circuit is required during normal operation. Electrical and feedback conductors exit through an angled swivel connector, which helps routing in confined spaces and reduces cable strain as the axis moves. The machine interface uses flange mounting, which keeps alignment accurate at the mounting surface and supports a compact installation length. Rotor position is reported by a resolver, providing robust feedback that tolerates electrical noise and supports stable drive control across changing speeds. A standard holding brake is included so the shaft can remain secured when input power is removed.

Length code 2 and motor size 3 establish the stator envelope, giving the unit a moderate overall mass that is easier to mount on compact machine structures. The mechanical output uses a keyed shaft, so torque can be transferred through standard couplings without special hub machining. Feedback precision remains within 10 angular minutes, which is suitable for medium-accuracy indexing and repeatable positioning tasks. When the axis is at rest, the brake supplies 2.5 Nm of static holding torque to help prevent unwanted movement. Because the design does not include an oil seal, the shaft area should not be exposed to pressurized lubricants, and applications with fluid exposure may require external sealing at the machine interface.
