Product Description:

The 8LSP93.R2015P644-3 is a three-phase synchronous motor supplied by B&R Automation within the 8LS Synchronous Motors series. As a drive element, it delivers electronically commutated torque for positioning and speed control tasks common in packaging lines, gantry systems, and process equipment. The 8LSP designation indicates a toothed shaft configuration that mates with keyed couplings, while the built-in fan supports continuous operation by moving air across the stator and frame.

This model’s continuous torque capacity is 148 Nm at the rated shaft speed of 1500 rpm, allowing stable mechanical output when operated at its nominal electrical load of 49 A. At that point, the motor converts electrical power to mechanical work equal to 25,133 W, giving a reference for drive sizing and thermal loading. When rapid acceleration or process upsets occur, the rotor can deliver up to 407 Nm, a short-term reserve that helps prevent stalls and maintain closed-loop control accuracy. Resolver feedback reports rotor position with six-arcminute precision to the drive controller, and the 0° connection direction keeps the terminal box aligned with the A-side bearing to simplify cable routing inside machinery.

The dynamic response is influenced by a rotor inertia of 290 kg·cm²; this value balances load matching against energy efficiency during frequent start-stop sequences. A maximum permissible axial force of 1126 N protects the bearings when the motor is belt-coupled or mounted vertically. Overall mass is 118 kg, so adequate structural support is required at both the mounting flange and the provided feet. Thermal saturation is slow, and the winding system reaches steady-state temperature only after 63 min, giving added headroom for intermittent overloads. An integrated oil seal limits lubricant migration along the toothed shaft, and the 269.9 mm flange dimension matches heavy-duty gear stages that require tight concentricity.
