1MS312B-4A-A1

Product Description

The 1MS312B-4A-A1 is a Bosch Rexroth motor stator. It is one of the two main components of 1MB motors, the other main component being a rotor. The 1MS312B-4A-A1 is specially designed for 1MB motors that have winding code 4A, frame length B and frame size 312. 1MB motors are liquid cooled asynchronous motors that are suited to applications such as processing centers, grinding and milling in machine tools and transfer lines. The liquid cooled motor stator gives 1MB motors a high power density. The coolant absorbs the power loss of the 1MS312B-4A-A1 and a major part of the power loss in the rotor. This power loss is transferred to a superordinate coolant in the refrigeration unit. Personnel that use 1MB motors should read and understand the relevant safety instructions and should also be familiar with appropriate produce use guidelines.

Bosch does not permit modification of motor hardware of firmware. Damaged motors or motor components should not be used or put in operation. The motor and motor components should be installed according to installation instructions that are included in the relevant documentation. 1MB motors are used with compatible drive controllers. Every drive controller has to be programmed prior to motor startup. The 1MS312B-4A-A1 and motors that use it as a component should only be used under the assembly, installation and ambient conditions as described in the product documentation. The 1MS312B-4A-A1 includes an aluminium cooling jacket. The electrical connection is via 1.5 meter cable. This cable is connected to the stator end with the larger output diameter. Handling of motor components such as the 1MS312B-4A-A1 stator, motor rotor and associated equipment should be done by trained personnel. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
