Problems solved by technology
The supporting force of the inner support frame is mainly the contact between the three high ribs and the inner diameter of the stator. The contact surface is small, that is, the contact force is small; and most high-voltage motors have a radial ventilation structure, which reduces the inner support frame. The contact area with the stator core, the extruded rubber skin and the coil at the radial air duct will be squeezed and the coil insulation will be broken, which affects the normal use of the stator core

The invention relates to a stator inlet case lifting device, in particular to a stator inlet case lifting device of a high-voltage motor. According to the technical scheme provided by the invention, the stator inlet case lifting device of a high-voltage motor comprises a fixed disc, evenly and symmetrically distributed connecting plates are arranged on the fixed disc, and all the end parts of theconnecting plates are provided with fixedly connected screw rods. Both ends of each screw rod are fixedly connected with the connecting plates and a stator core respectively, and the stator core can be placed in a base through the corresponding cooperation of the screw rods with the connecting plates and the fixed disc. Due to great bearing force, the stator core is placed securely, a corresponding coil on the stator core can not be damaged, and the normal use of the stator core can not be influenced.
Description
technical field [0001] The invention relates to a stator shell-entry hanger, in particular to a high-voltage motor stator shell-entry hanger. Background technique [0002] With the needs of the market, customers' demand for high-voltage three-phase asynchronous motors is increasing day by day. In the process of producing high-voltage three-phase asynchronous motors, manufacturers need to install the stator in the casing. Critical steps in the process of three-phase asynchronous motors. At present, the inner support frame is usually used to fix the stator core with windings, and the stator core is hoisted into the heated casing through the inner support frame. Therefore, the load-bearing capacity is limited and it is more dangerous. The supporting force of the inner support frame is mainly the contact between the three high ribs and the inner diameter of the stator. The contact surface is small, that is, the contact force is small; and most high-voltage motors have a radial...
