Industrial engine
An industrial motor is a motor that has been specially developed for industrial applications.
Built-in motors and stationary motors as well as motors for emergency power generators, industrial plants and commercial vehicles such as tractors , harvesting machines , industrial trucks and trucks are classically industrial motors .
The term is broad and includes both internal combustion and electric motors.
It is characteristic that industrial motors are not aimed at private users, but rather at third-party manufacturers who need robust motors to drive their products.
Internal combustion engines
In the case of combustion engines, there are both diesel and Otto and Wankel engines, the smallest and least powerful industrial engines are built into devices such as lawn mowers and chainsaws, while the main spectrum of combustion engines focuses on the power class up to approx. 60 kW, which are used to drive tires Vehicles come into consideration. The largest industrial engines are built into vehicles such as locomotives. In contrast to, for example, car engines, industrial engines often have different engine characteristics; the nominal speed , the torque and thus the specific displacement are reduced. Industrial engines can be developed either as pure industrial engines or car engines can be converted to industrial engines. Air-cooled single-cylinder engines dominate with powers up to approx. 15 kW – 20 kW, while in the power class from 20 kW – 60 kW there are mostly single or multi-cylinder engines with up to four cylinders. With powers above 60 kW, industrial engines are usually built in such a way that they can also be used as a vehicle drive without any problems; Many industrial engines in the power class above 60 kW are often derived from the commercial vehicle engine.
The so-called heavy-duty motors occupy a special position, as they are designed with a view to lower acquisition costs, versatility and, above all, robustness. Fuel consumption, pollutant emissions and specific power are irrelevant. These engines are usually four or six cylinder naturally aspirated engines .
