Three-phase special motors in flat design
Depending on their slim quadrangular design they are used in drives with small interspaces between spindles.
Especially strong design of bearings and shafts allows rated speeds up to 18 000 rpm when driven by a converter (300 Hz).
The heavy-duty bearing arrangement at the drive end and the – in comparison with the frame size – big diameter of the output shaft allow the direct mounting of drilling chucks etc.
These high-speed motors are mostly used in special machines for machining of plastics, wood or metals.
Mechanical design
Degree of protection IP 54 in accordance with DIN IEC 34, part 5. Motors are totally enclosed and surface ventilated.
Types of construction
Motors are available in feet or feet-flange version. They are to be fixed by using the taped holes in the motor feet.
The construction of the drive-end flange allows the mounting of a protecting device for the tools by means of taped holes.
Electrical design
Standard version: insulation class “F” according to EN 60034. The rated outputs mentioned below are valid for max. coolant temperature 40°C.
