Engaged in research on nitride semiconductor growth using the MBE method at Waseda University Graduate School. After graduating from graduate school in 2016, he joined a non-ferrous metal manufacturer.
Engaged in equipment maintenance and engineering work at metal smelting plants. Moved to a chemical manufacturer in 2022. Engaging in similar tasks.
A motor is a machine that converts electrical power into rotational motion, and is a very important piece of equipment in the industrial world used in many factories and plants.
However, motors also cannot convert 100% of the electrical power into rotary motion, as a percentage of the supplied electrical power is always released as heat. This loss is very small if only one motor is used. Since it is said that there are about 100 million motors in Japan, the loss is very large.
High efficiency motors have been developed to reduce these losses.
High efficiency motors are already widely available in many markets as replacements for existing motors. Uses of these motors include all products in which they can be used.
For this reason, high-efficiency motors are increasingly being used in pumps for water supply, roots blowers for airflow, and many other rotating equipment.
These high efficiency motors are equivalent to the IEC standard, which is a worldwide standard, and are generally defined as a premium efficiency class (IE3).
High efficiency motors consume less electricity than ordinary motors, which has the great advantage of addressing global warming and reducing power consumption, but there are also some points that require attention.
If you only need to replace the motor, you can generally just purchase the same one, but if the only alternative is a high efficiency motor, you need to be careful.
High efficiency motors tend to have a higher RPM, so connecting them to a pump or fan without any prior investigation may conversely increase the power consumption due to the increased power demand. Also, the starting current may be higher, so it is necessary to check in advance that there are no problems with the wiring, breakers, magnets, or other related equipment.
In addition, the torque generated will be higher, and the delta star starting system cannot be used, so it is necessary to check with the manufacturer of the equipment before replacing a conventional motor with a high efficiency motor.
However, it is becoming a corporate responsibility to reduce CO2 emissions as much as possible due to the problem of global warming.
If possible, replacing equipment with high efficiency motors will be highly appreciated as a company's environmental response.
