Product Description:

The Bosch Rexroth Indramat ADF Main Spindle Motors series includes the ADF160C-B05TA3-DD07-A2N1. This main spindle motor is used in machining centers to supply rotational power for cutting, drilling, and grinding operations. Its design supports continuous spindle duty where steady torque, accurate speed control, and stable thermal behavior are required during long production cycles. That operating profile makes it suitable for machine tools that run repeated acceleration, cutting, and deceleration sequences throughout a shift.

As a liquid-cooled asynchronous motor, it removes heat through a coolant circuit rather than external airflow, drawing heat directly from the stator jacket. This cooling method helps the motor maintain output in enclosed spindle areas where free air circulation is limited. The motor uses the 160 frame class with length code C, which fits spindle housings while leaving space for internal coolant passages. Its housing is prepared for flange mounting, allowing rigid attachment to the machine structure. Dynamic balance is rated R DIN ISO 2373, which helps reduce vibration during high-speed operation. Coolant connections use an axial rapid-action coupling, and power cabling exits toward Side A from a top-mounted connection area that helps keep terminals away from chips and fluid.

The control system uses digital servo feedback with an integrated encoder, giving the drive accurate rotor position data for closed-loop speed regulation and spindle orientation functions. That feedback path lets the controller respond quickly to load changes and maintain consistent spindle behavior during speed transitions. A plain shaft on Side A supports connection to precision spindle components, while the opposite end has no second shaft and no seal ring. Electrical power is delivered through a connector/plug interface that matches the manufacturer's quick-lock arrangement. The motor is supplied without a holding brake, so position retention during power-off conditions must be handled by the drive or the machine system. Standard rolling bearings support the rotor and help maintain smooth rotation across the operating speed range.
