What kind of motor to choose? How to choose the motor type?

How to choose a motor? Generally look at the following points:

1. It depends on the occasion you use, the load size, speed requirements, as well as the on-site power supply, site size and other conditions for selection.

Second, the power of the motor should be selected according to the power required by the production machinery, and the motor should be run under the rated load as much as possible. If the motor power is too small, it may cause long-term overload of the motor. so that its insulation is damaged by heating.

Even the motor was burned. If the motor power is too large, the output mechanical power can not be fully utilized, the power factor and efficiency are not high, and it will also cause a waste of electric energy. Depending on the power, determine whether to use a single-phase or three-phase motor, a high-voltage or low-voltage motor.

Then select the voltage level and capacity according to the power supply and the actual power size.

3. According to your requirements for the speed of the motor, such as after the load changes, whether the speed is allowed to change slightly, if it is allowed, it is recommended to use an asynchronous motor, otherwise, only a synchronous motor can be used, and whether there is a multi-stage speed change requirement, if there is a frequency converter or string resistance variable speed in the control.

Fourth, select the number of pole pairs of the motor according to the speed range.

5. Some motors with the same power also have large, medium and small machine bases, etc., which are selected according to the requirements of the site.

1. Basic principles of selection:

There is no unified standard for motor protection products on the market, and there are various models and specifications. In order to meet the different needs of users, manufacturers have derived a lot of series of products, which are of a wide variety and bring a lot of inconvenience to the selection of users; Users should fully consider the actual needs of motor protection when selecting the model, and reasonably select the protection function and protection mode in order to achieve a good protection effect.

2. Conditions related to selection.

1) Motor parameters: first understand the specifications and models, functional characteristics, protection type, rated voltage, rated current, rated power, power frequency, insulation level, etc. of the motor. These contents can basically provide a reference for users to choose the protector correctly.

2) Environmental conditions: mainly refer to room temperature, high temperature, high cold, corrosion, vibration, sand, altitude, electromagnetic pollution, etc.

3) Motor use: It mainly refers to the required characteristics of dragging machinery and equipment, such as fans, pumps, air compressors, lathes, oilfield pumping units and other mechanical characteristics of different loads.

4) Control mode: The control mode includes manual, automatic, local control, remote control, stand-alone independent operation, centralized control of the production line, etc. The starting methods include direct, step-down, star angle, frequency-sensitive rheostat, inverter, soft start, etc.

The main difference between cryogenic servo motors and normal motors is the temperature range in which they are designed and used. Ordinary Motors: Ordinary motors are motors that typically operate at room temperatures and are designed and manufactured with the temperature conditions of general industrial and household applications in mind.

The temperature range of these motors is typically 0??c (Celsius) to 40??c.

In this range, the performance and reliability of ordinary motors can be well guaranteed. Low-temperature motors: Low-temperature servo motors are specially designed and manufactured for use in low-temperature environments.

These motors are capable of operating in more extreme low temperature conditions and have higher cold resistance. Their temperature range is usually -40??c or lower, e.g. -60??

c。Low-temperature motors play an important role in applications such as extremely cold regions, high altitudes, refrigeration industry and scientific experiments...

Dear, glad to be your The choice of motor is decided according to the specific application, and there are many factors that need to be considered, and the following are some common selection points:1Power:

The required power needs to be taken into account when selecting a motor, which is usually determined by calculating the working negative cover load and rotational speed. The more powerful the motor, it is suitable for heavy loads and long working hours. 2.

Operating environment: Different operating environments, such as temperature, humidity and corrosion degree, can affect the service life of the motor, so it is necessary to choose a motor that can adapt to the environment. 4.

Installation location: Various types of motors require different installation methods, including vertical, horizontal, inclined or hanging installation, etc. Maintenance:

Maintenance cost is also one of the factors that need to be considered when considering the motor, including the ease of repair, daily maintenance, etc. Number of phases: The phase of the motor is generally divided into single-phase, three-phase and DC types, and the corresponding motor is selected according to the application scenario.

The above aspects are only part of the factors in the selection of motors, and the selection of motors in different application scenarios will also have unique needs and requirements. Therefore, in the actual selection process, other more specific needs need to be considered, such as space constraints, noise, etc. Weighing and comparing various factors to select the most suitable motor can ensure the use effect and production efficiency.
