1MS312C-4A-A1

Product Description

The Bosch 1MS312C-4A-A1 is a stator for 1MB motors. The stator is the motor component that is stationary. The rotor is the motor component that moves. The 1MS312C-4A-A1 is designed for 1MB motors that have frame size 312, frame length C and winding code 4A. 1MB motors are liquid cooled devices. The 1MS312C-4A-A1 includes an aluminum cooling jacket. The liquid cooling, which is usually water, flows through the jacket and absorbs heat that is dissipated inside the motor stator during motor operation.  The cooling system must be designed by the machine manufacturer in such a way that all requirements for flow, pressure, cleanliness, temperature gradient etc. are maintained in every operating mode. The cooling medium should be protected from pollution as well as changes to the chemical consistency and to the pH value.

Use of flowing water or hard water as the coolant is not permitted by Bosch. The deposits contained in hard water can damage the motor. A suitable additive should be added to the coolant that helps to prevent corrosion and promotes chemical stabilization. Use of aggressive coolants, additives and cooling lubricants can cause irreparable damage to 1MB motors. The performance data for 1MB motors is specified for 0 to 40 degrees Celsius ambient temperature and 0 to 1000 meters setup elevation. Operation of 1MB motor is not permitted at temperatures above 55 degrees Celsius or elevations above 3000 meters. The electrical connection on the 1MS312C-4A-A1 is through a 1.5 meter cable. This cable is lead out at stator end with larger diameter. Only qualified personnel should handle the 1MS312C-4A-A1 stator and other motor components. The 1MS312C-4A-A1 should only be stored in the vertical position. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
