Motor Housing of Manufacturers
1. Motor Housing Introduction
There are several materials of METALLECA® motor housing are classified iron, aluminum, steel, etc.
The manufacturing of the motor housing is adopted five kinds of casting processes: sand casting, gravity casting, low pressure casting, die casting, investment casting.
The process selection of specific qualitative is based on customer's technical standards, and then selects the reasonable production process.
The motor housing is asked to show high specifications in appearance, performance, assembly and other aspects, regardless of the general requirement.
There is a rigorous production process from blank to machining process.
In the casting process, we focus on mold design, pouring temperature, aluminum and molten steel clarity (exhaust gas, slag removal), pouring speed, blank surface treatment.
In the manufacturing process, we also consider the rationality and stability of fixture design, the machining precision of critical dimensions, the rationality of turnover (method, protection, etc.), and the standard packaging and pallet methods to the final shipment.

3.Motor Housing Feature And Application
Regarding to the type of power supply, it can be divided into DC motors and AC motors.
Electric machinery is that electromagnetic device implements the electric energy conversion or transmission according to the law of electromagnetic induction.
The circuit alphabet M (D as old standard) of the motor is represented generation of driving torque which is used as a power source for electrical appliances or various machinery.
Furthermore, the circuit alphabet G of generator is represented to convert mechanical energy into electrical energy.
Motor applications are quite extensive. For example, the low voltage below 48V applications have battery car motor, toy car, model airplane, electric shaver, etc. The applications of 110V & 220V have fan, hair dryer, treadmill, soymilk machine; medium voltage 380V & 660 have elevators, water pumps, conveyor, etc. The high voltage 6300V & 10000V applications have drainage pumps for drainage pump stations, air compressor motors for coal mines, etc.
Usually, the material of the motor housing is selected cast iron for the large one, and aluminum alloy for the small one.
Generally, gray cast iron is used. The gray cast iron can be divided into three kinds of material for motor housing: gray cast iron, malleable cast iron, and ductile cast iron. All of them have advantages of low cost and not easy to deform.
