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.

Embodiment Construction

[0019] Hereinafter, an example of the motor series according to the embodiment of the present invention will be described in detail with reference to the drawings.

[0020] figure 2 It is an overall vertical cross-sectional view comparing and showing the motors of the first basic series and the second basic series of the motor series according to the embodiment of the present invention, image 3 is along figure 2 Cross-sectional views of IIIa-IIIa, IIIb-IIIb in (A), (B).

[0021] exist figure 2 , image 3 Among them, (A) shows a structural example of a motor related to the first basic series with low efficiency, and (B) shows a structural example of a motor of equivalent capacity related to the second basic series with higher efficiency than the first basic series. For convenience, the illustrated motor of the first basic series is referred to as the first motor 12L, and the motor of the second basic series is referred to as the second motor 12H, and the first motors ar...

Abstract

The arrangement has a set of motors (12L) with different capacities and two base series units. One of the base series units includes an engine and an attachment part (22L) for attaching the motor to a partner unit. A stator core and a rotor core are not subjected to an insulation coating. The other base series unit includes a motor and a mounting section having dimension equal to that of the attachment part, and the stator core and the rotor core are subjected to the former basic series unit with small insulation coating and made of a laminated steel plate.

Description

technical field [0001] The invention relates to a series of motors. Background technique [0002] In recent years, for motors rotating at a constant speed, IEC (International Electrical Standards Conference) 60034-2-1, which stipulates the calculation method of efficiency, was issued in 2007, and the use of this calculation method to specify efficiency was issued in October 2008. Grade IEC60034-30. Here, the efficiency level refers to the classification of efficiency reference values ​​by level, and is defined as IE4 (ultra-high efficiency), IE3 (ultra-high efficiency), IE2 (high efficiency), and IE1 (standard efficiency) in order from the highest efficiency. [0003] With the advancement of energy saving, each country has shown a schedule for restricting the use of standard efficiency motors (IE1). However, the conventional IE1 type motor is still available for sale until it is actually restricted, and there is demand from users for its low price. In addition, there are ...
