Product Description

The 1MS160E-4B-A2 is a stator for Bosch Rexroth 1MB motors. 1MB motors are asynchronous motors that are designed for high-speed applications. Salient features of 1MB motors include torque ratings of up to 875 Nm, maximum shaft speeds of up to 20,000 RPM, excellent operating smoothness and easy machine integration. 1MB motors are maintenance-free and deliver high power density. Applications of 1MB motors include use as main spindles of machining centers and modern CNC machines. The 1MS160E-4B-A2 is a component of 1MB motors with the following specifications: 160 frame size, E frame length and 4B winding code. 1MB160 motors that include the 1MS160E-4B-A2 stator are rated for 33 Nm torque output, 1000 RPM speed, 3.5 kilowatts power output, 19 Amps rated current and 4000 RPM maximum speed.

The mass of the 1MS160E-4B-A2 stator is 9.4 kilograms. The permissible working temperature range is 0 to 40 degrees Celsius and the permissible storage temperature range is -20 to 80 degrees Celsius. The protection rating of the motor and it components is IP00: this rating implies no protection from solid or liquid ingress. The 1MS160E-4B-A2 includes an aluminum cooling jacket. 1MB motors are liquid cooled and 1MB160 motors are rated for 2.1 kilowatts power loss. All of the stator power loss and most of the rotor power loss is absorbed by the liquid coolant. The liquid coolant temperature at the inlet has to be between 10 and 40 degrees Celsius. The required rated of coolant flow for proper cooing is 3 liters per minute. Stators for 1MB motor such as the 1MS160E-4B-A2 should only be transported and stored in the vertical position. Stator storage in the horizontal position can damage the cooling jacket. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
