Product Description:
The 8LVA33.R0015D000-0 is a B & R Automation’s high-performing three-phase synchronous motor, which provides a nominal torque of 2.5 Nm to support constant load conditions. This motor has a resolver encoder system to support accurate measurement of the rotor position and maintain operation in closed-loop feedback systems.
The 8LVA33.R0015D000-0 motor operates at a nominal speed of 1500 rpm, enabling smooth synchronization with the common industrial frequency systems. At static or zero-speed operation, this motor is capable of supplying a stall torque of 2.6 Nm to hold mechanical force without rotating. During sudden acceleration or brief surges in demand, this motor produces a maximum torque of 7.2 Nm, allowing secure handling of high-inertia loads and temporary force peaks. This motor’s torque constant of 0.42 Nm/A specifies its linear torque development per ampere of current to facilitate precise torque control through current regulation. Its voltage constant of 25.13 V/1000 rpm guarantees a linear voltage-speed ratio, essential in drive compatibility and voltage feedback scaling. This synchronous motor boasts a stator resistance of 0.808 Ω, which adds to its thermal characterization and impacts current consumption at varying torque levels.
The stator inductance of this motor is rated at 3.3 mH to impact its dynamic response upon abrupt control changes. The 4.1 ms electrical time constant of this synchronous motor represents a high capability of current to enable rapid current response and smooth torque delivery in servo applications. A stall current of 6.3 A supports high torque delivery by this motor at zero speed while remaining within thermal limits. The 393 W nominal power rating allows this motor to be ideal for moderate power applications, to balance efficiency and output. The 8LVA33.R0015D000-0 synchronous motor is efficient within the operational ambient temperature range of -15°C to +40°C, and withstands climatic exposure having a relative humidity of 5% to 95%, non-condensing.
Frequently Asked Questions about 8LVA33.R0015D000-0:
