Motor Axial End-Float and Bearing Load
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
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 electric motor is an electromechanical machine that turns the magnetic field created by stator current into rotary motion on the rotor. The torque that lifts a hoist, drives a c... 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
