Choosing an Electric Drive Unit for the "Motor - Load" System
How to correctly choose an electric drive unit to ensure optimal and uninterrupted operation of the "motor - load" system? What factors should be considered to increase the reliability of the system? How can one reduce the starting current or ensure a smooth start? These are just some of the questions that clients ask when they contact us. In this article, we will examine these important aspects in detail.
The Importance of Correct Selection
The correct selection of an electric drive unit, taking into account the specifics of the drive, operating conditions, and the environment, is crucial for ensuring long-term and trouble-free functioning of the "motor - load" system.
The Use of Foreign Electric Motors
Today, the market offers a wide range of foreign-manufactured electric motors that can work with both new units and those that have already been used. This equipment has a high level of quality and reliability, but unfortunately, they are also prone to breakdowns.
European brand motors, such as ABB and Siemens, are manufactured according to international standards DIN and IEC, which affects their dimensions and operating parameters. In comparison, domestic electric motors of the AИP series are produced according to GOST standards, which significantly differ from European norms.
Additional Functions of Electric Motors
Foreign electric motors are often equipped with various additional functions, which distinguishes them from standard units. Information about additional features can be found in the factory designation of the electric motor modification. If necessary, you can contact the manufacturer or use special databases or configurators.
Ways to Choose Replacements for Broken Motors
Sometimes, even having the factory number, it is impossible to find a similar motor. In such cases, the replacement should be sought based on the following parameters:
- Type of electric motor - asynchronous or synchronous
- Electrical power in kilowatts
- Magnitude of operating voltage in volts
- Number of revolutions of the motor per minute
- Type of execution of the electric motor - foot or flange (dimensions)
- Diameter of the rotor element of the drive unit
- Options for the drive unit
- General photographs of the electric motor
After gathering this information, please send it to us via email. In a certain amount of time, we will prepare a commercial proposal for a new electric motor and frequency converter for it.
