Introduction

This section specifies the energy efficiency rating of the motor, involving a variety of motors rated for on-line operation (including buck start), as well as various amounts Constant voltage and frequency of all single-phase and three-phase low-voltage induction motor, including self-starting permanent magnet motor. This part not only applies to three-phase, cage induction motor, also applies to the rated online operation of a variety of motor technology structure, power range From 0.12kW ~ 1000kW motor. For a given output power and frame size, in general, the motor is designed to run directly on-line, 60Hz is easier than 50Hz To achieve high efficiency, see note 1. Note 1. Because the relationship between the motor size and the torque is not as linearly as the theoretical relationship between the output power and the rotational speed, as the frequency increases from 50 Hz to 60% increase in 60Hz. In the small and medium induction motor, the winding loss I2R is the main loss. When the torque remains constant, the winding losses from 50Hz to 60Hz are based This remains the same. Although the wind friction and iron loss will increase with the frequency increases, but in 4 pole and above the motor stroke friction and iron consumption accounted for a smaller proportion. Compared with the 50Hz motor, the 60Hz motor loss increases by less than 20% of the power increase, so the efficiency is improved. In fact, either 50Hz or 60Hz single-speed motor output power is designed according to the standard power level, such as IEC 60072-1. because Thus, the increase in motor rated efficiency does not always meet the principle of 20%. However, if the motors are optimized at their respective frequencies, then, at 60 Hz The advantage is still applicable. The difference in motor efficiency between 50 Hz and 60 Hz varies with the number of poles and the size of the motor. In general, three-phase cage induction motor power from the 0.75kW ~ 375kW, 60Hz when the efficiency of 50Hz than the efficiency of 0.5% to 2.5%. Only high-power 2P motor, due to iron consumption, wind consumption accounted for The proportion of large, at 60Hz when the efficiency is reduced. Do not expect all manufacturers to produce all the efficiency levels and all power levels of the motor. The user selects the efficiency level to refer to the actual run time. Due to increased inertia and starting loss, in the intermittent or short-term work system, Choose a high efficiency level of the motor is not necessarily energy saving. Note 2. How to use the high efficiency motor, application guide IEC /T S60034-31..2010 gives further useful information. In order to achieve a greater market share of satisfaction, in principle, the efficient motor should meet the relevant installation size and output power corresponding to the (Such as. seat size, flange size, etc.). The energy efficiency levels defined in this section are not subject to the size of the motor, so that all markets are born It is not possible to produce a high efficiency grade motor that meets the mechanical size standard. IE code is not limited to motors, but also can be applied to other products, such as. frequency converter and gearbox. Other products also apply to an identical system. IE1 is inefficient and IE5 is the most efficient. System combination products (such as electric drive systems) will have a comprehensive efficiency assessment. In order to avoid confusion, the assessment does not use IE code. The efficiency levels of 50 Hz and 60 Hz in this section are not always consistent with all poles and the entire power range.

1 Scope

This part of GB/T 32891 specifies that the range of IEC 60034-1 or IEC 60079-0 is designed to be controlled by a sine wave voltage The efficiency of single-speed motors is graded and meets the following requirements. a) Rated output power (PN). 0.12kW ~ 1000kW; b) Rated voltage (UN). 50V ~ 1000V; c) the number of poles. 2P, 4P, 6P, 8P; d) in the rated output power to ensure that its temperature limit to meet its insulation level can be long-term continuous operation; Note 1. Most of the motor ratings included in this section are S1 (continuous operation), however some motors are rated for periodic work as long as they are rated The output power can be continuously operated, also covered in this section. e) Ambient temperature range. -20 ℃ ~ 60 ℃; Note 2. Rated efficiency and efficiency ratings are given according to IEC 60034-2-1 at ambient air temperature of 25 ° C. Note 3. Motors rated at or below -20 ° C are generally considered to be of special construction and therefore are not included in this section. motivation. Note 4. This part includes the exhaust fan motor with temperature class ≤400 ℃. f) not more than 4000m above sea level. Note 5. rated efficiency and efficiency level is based on altitude ≤ 1000m. The efficiency limit established in this section is based on the frequency, the number of poles and the output power of the motor, and does not distinguish between the motor Technology, power supply voltage, or insulation for the need for variable frequency power supply, and even this type of motor technology simply can not achieve higher energy efficiency restrictions (see Table 1). This idea allows different motor technologies to have sufficient comparisons in terms of their energy efficiency potential. Note 6. Consider these factors when developing minimum energy efficiency standards (MEPS) for different types of motors. This section does not cover the efficiency of the power transmission system, especially including the power supply voltage harmonics, cable losses, filters and frequency converters Of the motor loss. This section applies to. a) Motors with flanges, feet and/or shafts of mechanical dimensions different from IEC 60072-1. b) Gear reduction motors with non-standard shafts and flanges. This section does not apply to. c) single-speed motors or multi-speed motors with 10 poles and more. d) A motor with a mechanical commutator (such as a DC motor). e) The combination of machinery (such as pumps, fans and compressors) can not be separated from the machine, even if the temporary cover and shaft extension bearings are provided A motor capable of conducting a separate test. This means that the motor should be. --- share with the drive device (except for connecting parts, such as. bolts) base parts (such as drive shaft or cover); - is designed to not be separated from the drive and can not be operated independently of the drive. This part does not include the separation of (drive) caused by the motor can not run. This section includes (TEAO, IC418) fully enclosed air-cooled motors, such as fully enclosed base surface cooling motors, with external ventilation To cool the motor. This type of motor efficiency test to remove the fan, with a fan and the original fan volume of the external fan to cool Motor. f) When the motor and the inverter are integrated (compact drive), the motor can not be tested separately when leaving the drive.
