Dynamic compact motors
In addition to high performance and dynamics, the most modern machine concepts also must be able to be installed in the smallest spaces. 8LVA three-phase synchronous motors from B&R were specially developed for these applications and provide users with the highest level of freedom in machine design by delivering maximum power density.

8LVA - Compact servo technology
The 8LVA motor series is the perfect choice when it comes to installing servo motors in extremely tight spaces. Equipped with either a resolver or digital EnDat 2.2 interface, these motors can meet the absolute highest demands. With their low moment of inertia, motors in the 8LVA series are designed to be highly dynamic and distinguished by their outstanding intrinsic acceleration characteristics. Additional noteworthy features include low cogging and a high overload capability. By default, these motors have IP54 protection but are also available with IP65 protection. They can optionally be equipped with a holding brake. Designed for use with ACOPOSmicro servo drives, these motors offer extremely high performance and are some of the most compact on the market. 8LVA servo motors are recommended for a wide range of applications and provide an optimal price/performance ratio in the power range up to 1 kW.

Properties
The special design of the surface allows it to be used in the food sector. Recesses in which liquids can accumulate were deliberately avoided.
- Ultra compact and highly dynamic
- High overload capability and low cogging
- Power range up to 1 kW for 80 VDC and 320 VDC DC bus voltage
- Self-locking connector system
- Robust industrial connectors with optimal EMC shielding
- 300° rotatable built-in double angular connector and single-cable solution (hybrid)
- Embedded parameter chipThe EnDat encoder for B&R motors contains all mechanically and electrically relevant information and data. This means that the user does not have to configure settings on the servo drive. As soon as the encoder is connected to the servo drive and the power supply to the electronics is switched on, the motor is automatically identified. The motor sends its nominal parameters and limit parameters to the servo drive. The drive then automatically determines the current limits and current control parameters required for optimal control of the motor. Only the speed and position controllers must still be optimized by the user. The integrated commissioning environment of B&R Automation Studio provides support for this. In addition to assistance during commissioning, routine service work is also simplified, and motors can be replaced without having to take extra time to set parameters.
