High temperature resistant motor is a new type of motor successfully developed by our company in the printing and dyeing machinery industry according to the requirements of users. It has a new appearance. It has added front and rear end cover injection and oil drain holes. At the same time, an oil rejection structure is added in the inner cover to prevent grease from squeezing into the inner cavity of the motor during refueling. And the standard oil pipe is connected to the tail of the motor, so that the user can normally refuel the bearing without disassembling the motor. When the service environment is ≤ 55 ℃, the outlet shaft, flange and other parts can work continuously under the harsh environment where the temperature rises to 250 ℃. All bearings are special bearings with high temperature resistance. When the motor runs for about 1500 hours, it should be filled with high temperature resistance grease to ensure the service life of the bearing. All motor materials are made of H-class insulating materials to prolong the service life of the motor and ensure the continuous production of printing and dyeing machinery industry. It has the characteristics of compact structure, reliable performance, convenience and durability.
