Product Description:

The 8lva22.r0030d000-0 is a three-phase synchronous motor produced by B & R Automation for the 8LVA Three Phase Synchronous Motors series. It converts drive current from a servo inverter into mechanical rotation. Automated stations can use this controlled rotation to position loads at the prescribed velocity and accuracy. The motor is suited to motion systems that require repeatable operation and closed-loop control.

Under rated conditions, the rotor turns at 3000 rpm while delivering a continuous shaft torque of 0.65 Nm and drawing 2.9 A from the drive. These nominal values align with the electrical output of midsize motion controllers and provide a rated mechanical output of approximately 204 W. A back-EMF gradient of 13.61 V/1000 rpm indicates how the induced voltage presented to the inverter increases with speed. Copper loss is influenced by the phase resistance of 2 Ω, while a stator inductance of 4.1 mH affects magnetic energy storage. When rotation is blocked, the motor can accept a stall current of 3 A to hold a load while developing 0.68 Nm of stall torque. Position feedback is provided by an integrated resolver that reports the rotor angle with a precision of 10 angular minutes, allowing the control loop to maintain steady speed despite load disturbances.

The shaft can deliver up to 2 Nm for short intervals when supplied by a peak phase current of 10.3 A. Current rise within the windings follows an electrical time constant of 2.1 ms, so torque can be established quickly after a command. The electromagnetic design provides a torque constant of 0.23 Nm/A, supporting predictable proportional control when used with the resolver feedback. The motor has size code 2 and length code 2, providing a compact footprint for machine layouts that use several coordinated axes. Its short-term torque capacity supports rapid acceleration when the connected mechanism demands more torque than is available during continuous operation.
