Product Description:
B&R Automation's 8LVA33.B1021D200-0 is a three-phase synchronous motor from the 8LVA Three Phase Synchronous Motors series in the 8LV Servo Motor family. It is used in industrial automation to drive rotary axes that require stable torque, accurate speed control, and repeatable motion under closed-loop servo operation. The motor is intended for direct connection to B&R inverters, where it supplies mechanical output for packaging, material-handling, and assembly equipment that must accelerate, index, and stop with consistent response.
Thermal management relies on self-cooling, so external airflow or liquid jackets are unnecessary when the motor runs at its nominal electrical load. The integrated brake provides 4.0 Nm of static torque, which helps secure vertical or suspended loads during power-off intervals. Rated operation reaches 2100 rpm, a speed suited to general-purpose servo axes in packaging and robotics. Position feedback is generated by an EnDat 2.2 inductive sensor, which communicates absolute position data without using fragile optical disks. The motor uses motor size 3 with a matching length of 3, and torque is transmitted through a smooth shaft. The housing has no oil seal, so external sealing is needed if the installation is exposed to splash or contaminants. Safety functions specified in IEC 61800-5-2 are not embedded, so functional safety must be handled outside the motor.
The encoder assembly is battery-backed, enabling true multi-turn acquisition over 65536 revolutions without homing after power loss. The feedback system has a resolution of 19/16-bit for single-turn and multi-turn measurement, and angular deviation stays within ±120 arcsec for fine positioning in high-gain servo loops. Power conductors and feedback lines leave through separate interfaces to reduce crosstalk, and routing is simplified by a built-in double angular swivel connector that can be rotated to suit the cabinet layout. This separation helps preserve signal quality when power and feedback cables must run through compact machine spaces.
