Because the internal elements will definitely release a major feature that converts electrical energy into mechanical rotational motion, as well as electromagnetic fields. As a result, movement and input power should be maintained very specifically, therefore, each position of the part needs to be positioned very possibly. The gap between blades, bearings, stators, air gaps, windings, and electric motor housing made between them should be as small as possible.
Regarding no leakage, we consider this requirement from two aspects. One aspect is about bubbles in the electric motor housing. In this case, it should be a strict requirement. On the other hand, the gap after assembly needs to be extremely small to prevent any lubricating oil from flowing out of the sealed cylindrical tube.
The main purpose of using a motor is to obtain a continuous and stable supply of mechanical motion. In order to keep the entire motor stable, portable real estate cannot be missed. Lightweight aluminum is the best choice in this market. For mass production with normal demand, die casting solutions are the most cost-effective. First-class, small-scale manufacturing, lightweight aluminum extrusion and CNC processing, can truly radiate the surface area and show the best way of high-end top quality.
When the motor is working, all the main components that generate power demand rotate upward, forcing the relevant supports of the components to continuously contact the interior of the real estate with mechanical power. Due to the long procedure, the touched face is conveniently worn. The electric motor housing surface is made of aluminum, very smooth, and the roughness is very small, electric motor housing can definitely reduce the conflict between the contact surfaces and prolong the service life.
The aluminum alloy is first examined, then a chemical structure analysis is executed using a spectrology device. Next, the alloy is thawed by heating it to a temperature of roughly 680ºC, and after that infused right into the mold and mildew in the die casting equipment. On cooling, the covering is removed as well as deburred using pneumatic devices. The shell is then fired blasted, machined and also hand worked to make certain a smooth and also finish with no burrs.
The shell is heated up by induction to expand the size and the windings are then decreased in; they are secured into location as the covering cools. Amtech makes certain that the inner size (6.286- 6.288) of the shell is purely based on specifications, since if the covering is oversized the motor will fail. We for that reason measure the size with respect to the four mounting holes of dimension 8.39 ~ 8.63.

Finally, the die cast motor covering is cleaned up by utilizing reducing representatives, acid and ultrasonic methods, and the piece is rinsed between each cleansing cycle. The electrical motor housing unit is then dried in an oven, as well as after a last assessment by the Quality assurance Division, is packed as well as sent to the consumer.
