8LSA35.R0030C100-0 by B & R Automation

B & R Automation's 8LSA35.R0030C100-0 is a three-phase synchronous motor supplied within the 8LS Synchronous Motors series. As a servo-grade rotary actuator, it converts commanded drive current into controlled torque and speed for positioning axes, conveyors, or indexing tables in industrial automation cells. The unit follows the 8LSA configuration, meaning a standard mechanical build without reinforced bearings, and it is intended for integration wherever compact, resolver-based feedback and flange mounting are acceptable.

The motor reaches a rated velocity of 3000 rpm, allowing direct coupling to moderate-speed loads without external gearing. Its flange face measures 91.3 mm, so it mates to machinery that follows IEC size conventions. Positional repeatability is supported by 10 arcmin of mechanical precision, adequate for packaging and material-handling duties that do not demand sub-arcminute accuracy. Cabling exits through a straight top connector, simplifying vertical cabinet layouts, and the winding temperature is limited by self-cooling through free air circulation, eliminating the need for forced ventilation. Connection hardware is provided as a plug-style connector to shorten assembly time, and the shaft includes a DIN key for torque transfer.

Feedback is delivered by a resolver, giving absolute rotor angle information over the full speed range without requiring battery backup. The housing fastens to the machine through a mounting flange, and overall body length corresponds to length code 5, which places the stack in the middle of the series' power spectrum. The shaft end is supplied with a key, ensuring slip-free coupling to pulleys or couplings. A holding brake and an oil seal are not present, so external load-holding methods and environmental gaskets must be considered when the motor is installed in vertical axes or splash zones.
