Product Description:

The 1AD180L-B502-4A100 is an asynchronous AC spindle motor produced by Bosch Rexroth Indramat for the 2AD 3-Phase Induction Motors series. It serves as the prime mover on machine-tool and packaging spindles, converting inverter-supplied electrical energy into controlled rotary motion for cutting, drilling, or winding stations. Integrated encoder feedback lets the drive regulate the shaft with closed-loop precision, while the motor’s frame and mounting interface allow direct coupling to high-speed production equipment. Because it is intended for inverter duty, the motor is suited to applications that require repeatable acceleration, deceleration, and stable speed regulation under changing process loads.

During operation, the motor receives 220 VAC from a compatible drive, generating the magnetic field needed to reach a maximum speed of 4000 rpm. An internal axial blower forces air through the cooling channels so copper and iron losses are removed before they elevate winding temperature. Rotor position is detected by an incremental encoder, and its pulse stream supports accurate velocity control and homing functions. Thermal protection is supplied by an embedded thermistor that signals the drive when winding temperature approaches its limit, allowing power reduction or shutdown before insulation damage can occur. This feedback and temperature monitoring help the spindle remain responsive during changing load conditions.

The stator uses a three-phase winding connected in a Wye configuration, which helps maintain balanced line currents and provides a central neutral point for protective relays. A 4-pole magnetic layout supports smooth torque at low speeds when the motor is operated with vector control. Mechanical dimensions follow size code 180, which corresponds to the flange diameter, shaft height, and bolt circle used across the series. The unit is supplied without a holding brake, so stationary positioning during power loss must be handled by external clamping or by the drive’s static torque. The mounting pattern allows the motor to fit machine layouts built around this frame size without requiring special adaptation.
