Product Description

The Bosch 1MS240D-4A-A1 is a motor stator. It is compatible with 1MB motors that have the following specifications: winding code 4A, frame length D and motor frame size 240. Bosch 1MB motors are liquid-cooled asynchronous frameless spindle motors that are used as direct drives in motor spindles. The position of the motor between the main spindle bearings give the motor spindle a high rigidity. Typical applications for 1MB motors include turning, milling in grinding machine tools, processing centers, and transfer lines. Bosch 1MB motors are used in combination with a mains spindle control device. Due to the liquid-cooled stator, the 1MB motor deliver high power density. The coolant fluid absorbs the power loss of the stator and a large portion of the rotor power loss. The heat absorbed by the coolant is transferred to a superordinate coolant in the refrigeration unit.

The 1MS240D-4A-A1 includes an aluminum cooling jacket. The electrical connection on the 1MS240D-4A-A1 is via a 1.5-meter cable that is conducted through the stator end with bigger exterior diameter. Protection rating of the motor stator is IP00. This rating indicates that the stator is not safe from solid or liquid ingress. The 1MS240D-4A-A1 is designed for ambient temperature ranging from 0 to 40 degrees Celsius. During storage the area where the 1MS240D-4A-A1 is kept should have an ambient temperature that ranges from -20 to 80 degrees Celsius. During storage the 1MS240D-4A-A1 should be protected from vibrations and corrosive atmosphere. The 1MS240D-4A-A1 must be kept vertical during storage to protect the cooling jacket. If a stator is found to be damaged, it should not be put into operation. The stator must be handled by trained personnel only. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
