Knowing the basics is essential to choosing the right motor. In this category you will find guide content on the electric motor working principle, motor types, efficiency classes and selection criteria. Get to know the world of motors with the technical knowledge of the DRG Motor expert team.
For the right motor, power (kW), speed (rpm), efficiency class, body material and mounting type should be considered together. Our high efficiency motors page guides you on efficiency and the power and speed options page on power/speed.
What is the difference between asynchronous and synchronous motors? In an asynchronous motor the rotor turns slightly slower than the magnetic field; in a synchronous motor it turns at the same speed.
Why is motor efficiency important? High efficiency does the same work with less electricity, lowering operating costs.
DRG Motor supports businesses on both the product and knowledge side. By reviewing this guide content you can choose the right motor more consciously, and contact us via drgmotor.com for technical questions.
Motor efficiency is classified as IE1 (Standard), IE2 (High), IE3 (Premium), IE4 (Super Premium) and IE5 (Ultra Premium). The higher the class, the lower the energy loss and the greater the savings. Which class suits you is determined by your running hours and power needs; review our guide content for details.
Which mounting type is needed? Foot (B3) mounting is used in most applications, while flange (B5) or combined (B35) mounting is preferred where direct coupling is required.

An IE3 motor is an asynchronous electric motor that meets the "Premium Efficiency" class of the IEC 60034-30-1 standard. Mandated in many countries as the minimum efficiency for ce... More Details

When you look at the nameplate of an electric motor, you encounter many markings such as the insulation class, the protection class, and the efficiency class. Among them there is a... More Details

Not all of the sound you hear from a running electric motor is mechanical in origin. Alongside bearing friction and fan noise, there is also magnetic noise, which is born in the mo... More Details

The shaft of an electric motor does not just rotate; even if only by a very small amount, it has the freedom to move back and forth along the axis, that is, along the shaft. This m... More Details

While an electric motor is running, the heat it produces keeps condensation from forming inside. The real danger begins when the motor stops: as the machine cools down, the humid s... More Details

The DRG IE3 motor difference comes down to one principle: doing the same work with less energy. By reducing its losses compared with IE1 and IE2, an IE3 Premium motor delivers a la... More Details

The frame of an electric motor is not just a shell holding the windings and bearings; it governs heat dissipation, vibration behaviour and mechanical strength. Choosing between a c... More Details

Efficiency in an electric motor shows how much of the electrical energy drawn from the grid becomes mechanical power at the shaft end. The difference turns into heat as winding, ir... More Details

The codes you see on an electric motor's nameplate, such as IP55 or IK08, represent two separate languages that describe how durable the motor is against the outside world. The IP ... More Details

When an electric motor is fed from the mains, the high current it draws at the moment of starting often goes unnoticed, because the city grid behaves like an almost unlimited sourc... More Details

An electric motor runs healthily only if the energy feeding it is as sound as the motor itself. Under ideal conditions, the voltage coming from the grid should have a constant ampl... More Details

When selecting an electric motor, the choice between an aluminum housing and a cast iron housing is made by the application's load, the need for portability and the operating envir... More Details

The rotation direction of an electric motor may look like a minor detail at first glance, but in many applications it is a critical matter that determines whether the job can be do... More Details

The lifespan of an electric motor largely depends on choosing the right electrical equipment to power and protect it. No matter how high the quality of the motor itself, if a suita... More Details

In an electric motor the housing directly determines heat dissipation, mechanical strength and service life. The two most common housing materials in industry are aluminum and cast... More Details
