Liquid-cooled Dietz motors

Best power density with compact and smooth housing

November 11, 2020

Self-ventilated or forced-ventilated motors of the IC 411 or IC 416 standard are part of everyday life and everyone knows them. The standard motor, or at least the drive of many industrial machines that looks like a standard motor, has a fan guard, a fan blade underneath it and associated cooling fins on the circumference of the stator housing.


A high performance machine for specialists

October 23, 2020

From the outside you usually cannot see what is inside.
Often also with three-phase motors, which are operated by means of frequency converters from 50Hz or 60Hz to more than 300Hz. Fans cover, ribbed housing... From the outside, everything points to a "normal IEC motor"...

September 15, 2020

High flowrate and enormous pressure increase?
The Dietz SB High Performance Blower for frequency converter operation can do both! On the one hand, high flow rates and good efficiency over a wide range of characteristic curves, on the other hand high pressure increase or decrease...

Temperature lock

Prevent heat transfer successfully

July 09, 2020

To prevent heat transfer from a machine to a drive motor, often so-called temperature locks are used. These effectively decouple the components by using the smallest possible contact surface and connection...

Speed monitoring

Times they are a-turning

June 05, 2020

Electric drives in machines do not always have to provide the required power, speed and torque. Speed monitoring or a so-called standstill monitoring are attributes that are often required by the machine control, also with regard to the safety of humans and machines...
