Product Description:

The 8MSA5M.R0-V8011 is a three-phase synchronous motor from B&R Automation in the 8MS Three Phase Synchronous Motors series. It is intended for servo axes and coordinated motion stages, where it converts electrical input into precise mechanical rotation for packaging machines, material-handling lines, and general factory automation equipment. As a synchronous design, it responds to commanded current with controlled torque and speed, making it suitable for indexing, positioning, and synchronized conveyor tasks. Its compact frame and integrated position feedback support closed-loop control while helping conserve installation space.

The motor uses a self-cooling thermal concept that dissipates heat through the housing without an external blower. With a motor size of 5, it fits mid-range machine envelopes while still supporting the shaft extension used in this series. Position feedback is handled through a resolver interface, and the drive interprets the sinusoidal signals for immediate rotor angle tracking. Sensor nonlinearity is limited to ±1 angular minute, which helps keep cyclic position error low during interpolation moves. Because cooling is handled by the housing, surrounding machine layouts do not need separate fan hardware at the motor.

The mechanical envelope uses motor length M and has a medium relative rated torque, placing its continuous output between the lighter and higher-power versions in the series. This torque class suits duties that need more sustained output than light versions without moving to the highest rating in the range. Resolver precision is rated at ±10 angular minutes, giving the controller feedback quality suitable for low-speed regulation and coordinated motion. The sensor hardware uses the BRX resolver type, which keeps interface matching consistent within the 8MS platform. In coordinated axes, the resolver signal gives the drive continuous rotor angle information during acceleration, low-speed operation, and position holding.
