Must-read guide to choosing a car wash machine in 2023: universal or induction Motor

The emergence of high pressure washer has greatly facilitated people's clean living, allowing even stubborn stains to be easily washed away, saving time and effort.

When selecting a high pressure washer, we often find ourselves torn between choosing an induction motor or a universal motor. As the saying goes, "An outsider looks at the pressure, but an expert looks at the motor." The selection of the motor should not be taken lightly. As the two main types of motors in the current market for high pressure washer, each has its own advantages and disadvantages. So, which one should be purchased?

Universal motor structure

Induction Motor Structure

The distinct structures of universal and induction motors determine their unique characteristics, each with its own advantages.

Comparison of characteristics between universal and induction configurations

The high rotational speed of the  universal motor and the low rotational speed of the induction motor bring about distinct differences, and considerations can be made when purchasing based on the following aspects.

Lightweight design:

Universal motor, with a speed of over 15,000 revolutions per minute, the high speed results in a lightweight design, with the overall machine typically weighing between 3 to 14 kg;

The speed of the induction motor is low, around 2800 revolutions per minute, and it has a larger size; the net weight of the entire unit typically ranges from 6 to 28 kg.

Volume:

The universal motor, due to its high speed, produces a sound level around 85 decibels;

Induction motor, the sound level is around 75 decibels, and it can almost be drowned out by the noise of high pressure water jets.

Quality-price ratio:

At the same price point, the pressure-flow characteristics of the universal motor are superior to those of the induction motor;

Life:

The induction motor with no carbon brushes, long maintenance cycle, and long lifespan.

Overall, the respective advantages of induction and Universal motors are already quite evident. It's about choosing what is best suited to one's needs based on benefits and avoiding drawbacks. Emphasizing value for money, selecting a universal motor-type car wash machine is a safe choice; for example, the RY-B2 model.

It is sensitive to volume levels, so it is recommended to choose an induction motor-based high pressure washer. Examples include the RY-P16.

With the continuous improvement and maturity of technology, high-end series-excited high-voltage cleaning machines can also achieve remarkable noise reduction; induction motor-type cleaning machines can also offer portability and high-performance motor parameters. The ultimate stability, durability of these machines is closely related to the selection of core components. The high-quality requirements of Ruiying are reflected in the meticulous craftsmanship of the motor casing, as well as the selection of components such as coils, gears, and enameled wires, all of which are strictly controlled to ensure solid materials are used.
