8LVA23.R0030D300-0 by B & R Automation

The 8LVA23.R0030D300-0 synchronous servo motor is produced by B&R Automation and belongs to the 8LVA Three Phase Synchronous Motors series. This three-phase unit is designed to deliver precise closed-loop rotation for pick-and-place heads, indexing tables, and other motion axes that rely on coordinated speed and torque control. A resolver feedback element supplies rotor position to the drive, allowing the motor to operate within a decentralized automation platform. Because it is a synchronous servo motor, the connected drive can regulate torque and speed with direct rotor position feedback.

During continuous operation, the motor reaches a nominal speed of 3000 rpm and produces a nominal torque of 1.3 Nm. These operating values are achieved with a phase current of 5.8 A through windings with 0.83 ? of resistance and a stator inductance of 2 mH, which affects current rise time and servo response. A torque constant of 0.23 Nm/A links motor current to shaft torque, and a back-EMF constant of 13.61 V per 1000 rpm indicates the voltage generated as speed increases. Position accuracy is 10 angular minutes, and the RE-15-1-J04 resolver is connected through separate encoder and power leads routed by a built-in double angular swivel connector.

For short-term overloads, the motor can deliver a peak torque of 4 Nm and a surge current of 20.7 A. The integrated brake provides 2.2 Nm of holding torque for parked positions, and the rotor moment of inertia is 0.26 kg cm², which supports rapid acceleration with limited drive effort. Its low inertia helps the axis respond quickly during frequent indexing or short positioning moves. The motor is self-cooled, has size code 2 and length code 3, weighs 1.45 kg without the brake, uses a keyed shaft without an oil seal, and reaches a stall torque of 1.35 Nm.
