Product Description:
The 8DI330.D90450001-1 is a three-phase servo motor manufactured by B&R Automation for the 8DI ACOPOS Motors series. The unit produces precise torque and supplies velocity feedback to the matching ACOPOS drive controller, enabling closed-loop positioning of gantries, packaging lines, and robotic joints. By incorporating fully digital feedback within the motor housing, it streamlines cabling and supports compact machine layouts in industrial automation.
Position information is delivered by a multi-turn encoder that tracks up to 4096 revolutions with 12-bit resolution; this capacity allows the absolute position to be recalled after a power loss without external batteries. Communication with the drive occurs through the EnDat 2.2 protocol, and the sensing element uses a multi-turn functional safety design to support position monitoring on safety-rated axes. The encoder uses an inductive operating principle, which tolerates oil mist and magnetic debris better than an optical disc. During continuous duty, the rotor can reach 4500 rpm, supporting the cycle times required for high-speed pick-and-place cells. Module Size Code 3, Module Length Code 3, and Configuration Version 1 identify the mechanical stack. No additional POWERLINK port is fitted because the hybrid feedback cable carries power and real-time data.
For mechanical integration, the motor has a smooth shaft with a special-purpose 14h6 fit and a length of 30 mm, allowing direct coupling to precision gearheads. An axial load of up to 1400 N can be applied without exceeding the bearing limits, and angular positioning accuracy remains within ±120 arcseconds. The housing withstands production shocks of ≤2,000 m/s² and vibrations of ≤400 m/s² or ≤600 m/s², allowing installation on moving carriages. Hardwired safety technology supports emergency-stop functions. The motor does not have a holding brake, so an external mechanism or drive-applied torque must secure a stationary load. The shaft does not have an oil seal, which minimizes rotational drag in applications where additional sealing is unnecessary.
