Division industrial motors The division industrial motors include development, construction, production and sales of mainly asynchronous three-phase motors. Emphasis is not made on the manufacture of standard motors and mass production, we rather try to solve together with our customer his individual drive needs. We construct independently of quantities - we mainly build single units and small series, and this in shortest delivery times. Krautler supplies asynchronous motors as special mechanical and electrical solutions, water-cooled motors, synchronous reluctance motors, torque and coiling...

Division boat motors The construction of electric boat motors started in the 80‘s. First for own consumption and in reality only because no product on the market satisfied the high requirements of the company founder Oswald Krautler. Nearly 40 years after the first boat motor from Krautler, these motors gained in the meantime worldwide recognition. No wonder that sailing and motorboat fans link „Krautler“ to commitment to quality and performance. With our „groove" in motor construction we show competence and quality. Especially in motors for boat drives, our range of electric motors for sailing...

Division repair The division repair includes the areas of preventive repairs servicing, reporting and the classic repair. The failure of an electric motor during use can lead to significant failure costs. In order to avoid this failure costs, we offer our customers the option of preventive maintenance work. In this work, wear and tear parts such as seals, bearings are replaced and the winding is tested. Through years of experience in the field of electric motors production and assembly, it is possible for us to identify development or production errors also from other manufacturers and to demonstrate as...

In the last years there has been a significant improve and expand of diversity and power of electric propulsion submersible motors. Here you will find some explanations for a better distinguish of different motor variants and a description of the components which are included in the standard version. For an application with low power requirements we recommend the GP engine. The GP motor is a permanently excited DC motor. For a power requirement of more than 2,4kW we recommend the AC engine. The AC motor is a brushless three-phase asynchronous motor. All electric drives with Submersible motors...

Delivery programme submersible flange motor fixed propeller folding propeller High performance The efficiency of a ship propulsion system is dependent on the shaft speed and the proper selection of the propeller. By the superior torque curve of an electric motor to a gasoline engine two or three-blade propeller can be used at low shaft speed. Because of this principle, a very high thrust is developed even for small drives. Both, the AC and the GP engine are available with a fixed or folding propeller. Kräutler AC drives are also completely maintenance-free. Low noise level The luxury of being...
