For the end customers of the motor, they are very concerned about the size of the motor current, and believe that the smaller the current of the motor, the more power will be saved, especially for ordinary and efficient motors, the current size is compared.
The scientific approach is: the same specification motor is running under the same working conditions, and the power consumption of the same workload is evaluated within a certain period of time. In other words, small current does not necessarily save energy, and large current does not necessarily have low efficiency.
Measures to improve the efficiency of the motor. The energy saving of the motor is a system engineering, involving the whole life cycle of the motor, from the design and manufacture of the motor to the selection of the motor, operation, regulation, maintenance, scrap, to consider the effect of the energy-saving measures from the whole life cycle of the motor, at home and abroad in this regard mainly consider from the following aspects to improve the efficiency of the motor.
The design of energy-saving motor refers to the use of optimization design technology, new material technology, control technology, integration technology, test and detection technology and other modern design means to reduce the power loss of the motor, improve the efficiency of the motor, and design an efficient motor.
Efficient motor from the design, material and process to take measures, such as the use of reasonable fixed, rotor slot number, fan parameters and sinusoidal winding and other measures to reduce loss, efficiency can be increased by 2%-8%, an average increase of 4%.
From the perspective of energy conservation and environmental protection, high-efficiency motors are the current international development trend, and relevant regulations have been promulgated in the United States, Canada and Europe.
From the perspective of international and domestic development trends, it is very necessary to promote China’s high-efficiency motor, which is also the requirements of product development, so that China’s motor products keep up with the international development trend, but also conducive to promoting the industry’s technological progress and product exports.
