Product Description:

The 61BM330BBAT0 is an industrial servo actuator produced by Sanyo Denki as a member of its BL Super Servo Motors series. Serving as a rotary prime mover in automated transfer lines, this motor combines a precision encoder with a permanent-magnet rotor to supply controlled torque and speed to connected machinery. It translates drive output signals into repeatable mechanical motion for indexing tables, packaging stations, and general CNC axes.

The unit’s continuous shaft output is rated at 4.3 kW, supplying sufficient mechanical power for medium-inertia loads that require constant velocity under closed-loop control. Position feedback comes from an internal encoder that produces 131072 counts per revolution, allowing the drive to detect angular changes much smaller than one-tenth of a degree. The sensing element is an ABSOSYN resolver-based device, and its signals pass through a rugged 17-pin MS connector secured to the motor end bell. The encoder also retains absolute single-turn position, allowing the drive to recover the shaft angle after power is restored. This feedback arrangement supports accurate indexing without requiring a complete homing routine after every startup.

The feedback interface provides serial and incremental signals, including incremental quadrature data for drives that require high update rates. Identification code E10B171103 identifies the specific sensing head installed in the motor. The unit is classified as an AC servo motor and supports sinusoidal commutation through a compatible inverter platform. Its control data include matching values for torque constants, thermal thresholds, and feedback timing, which allows the drive to regulate the motor without manual signal scaling. The encoder connection also provides a secure industrial interface for feedback transmission in machinery exposed to vibration and repeated operating cycles.
