Product Description:
The ADF134B-B05TA0-BS07-A2N1 main spindle motor is produced by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor intended to drive machine-tool or production spindles directly in automated lines. The frame size 134 and length code B give the rotor and stator enough axial depth to support high continuous power, while winding code BS matches the electrical characteristics required for compatible inverter operation. This arrangement suits automated machining systems that need stable torque delivery and accurate speed regulation under changing load conditions.
The rotor is balanced to R (DIN ISO 2373) balance grade, which helps limit residual forces that could affect surface finish during spindle operation. Heat is removed through a liquid-cooled jacket, and coolant enters through an 1/4" axial coolant port that supports rigid tubing connections. Mechanical attachment uses flange mounting, so the motor face bolts directly to the spindle housing without intermediate plates. Electrical conductors use a power exit on side A, and a sealed connector keeps the phase terminals isolated during operation. Standard rolling bearings support the shaft, and the lack of a seal ring reduces friction where external splash protection is already present.
Position and speed data are returned over digital servo feedback, so the drive controller can close the velocity loop with encoder signals from the motor. Because the unit is supplied without a holding brake, any static clamping force must be provided by the machine spindle or an external brake module. The drive end uses a plain shaft, and there is no second shaft on side B, which helps keep overhang length low in compact headstocks. A top-mounted power housing keeps the high-current connector clear of coolant hoses, while internal shields retain bearing lubrication without a shaft seal ring. This layout also leaves the connection area easier to access when the motor is installed in a confined spindle head.
