Motor series

Abstract

The invention provides a motor series capable of guaranteeing the interchangeability of motor having different efficiency. The installation interchangeability includes avoiding interference with peripheral devices in a broad sense. The motor series provided by the invention includes a plurality of motors having different capacitors, wherein the first basic series having low efficiency is provided with a first motor (12L). The first motor is provided with a specific installation part (22L) used for installing the motor onto a target component under a specific volume. And at least one of a stator core (14L) and a rotor core (16L) is not provided with an insulating coating layer. A second basic series having high efficiency than the first basic series is provided with a second motor (12H). The second motor is provided with a capacity equaling to the specific volume and is provided with an installation part (22H) in the same dimension with the specific installation part (22L). And the components that are not provided with the insulating coating in stator core (14H) and a rotor core (16H) are formed by laminating steel boards provided with the insulating layers.

Description

Technical field [0001] The invention relates to a series of motors. Background technique [0002] In recent years, for motors that rotate at a constant speed, the IEC (International Electrical Standards Conference) 60034-2-1, which specifies the calculation method of efficiency, was issued in 2007, and in October 2008, it was issued to use this calculation method to specify the efficiency. The level of IEC60034-30. Here, the efficiency class refers to the classification of efficiency reference values ​​by class, which are defined as IE4 (ultra-super-efficient), IE3 (super-efficient), IE2 (high-efficiency), and IE1 (standard efficiency) in order from the highest efficiency. [0003] With the development of energy saving, every country has shown a schedule to restrict the use of standard efficiency motors (IE1). However, the conventional IE1 motor can also be sold before the actual restriction, and there is user demand due to its low price. In addition, there are models and applic...

Problems solved by technology

However, not only that, but for the point that "the appearance is not interchangeable (cannot be accommodated in the space previously accommodated)" with the IE1 standard motor that has been widely used in the past, in the near future, it may be used in various actual bad situation

For example, even if the life of the main mechanical device itself is still very long, but only when the motor is in bad condition, and the manufacturer has terminated the production of IE1 in time and there is no stock, if the space cannot accommodate the IE2 motor of equal capacity, then consider that the entire main mechanical equipment must be scrapped

This "interchangeability in appearance (interchangeability in a broad sense)" problem can also occur between IE2 and IE3, and between IE3 and IE4.
