Frame material:

Can be selected in accordance with its intended use

Randax® electrical machines are tailored according to the requirements of the customer and the application, providing the customer with freedom in product design. In every case, this means that the frame materials, connecting flanges etc. are specified in cooperation with the customer.

The motors or generators are based on permanent magnet technology and are always controlled by frequency converters. Their efficiency is always in the highest category, IE4, and they are available in water or air-cooled versions.

The power and speed of the motor are designed according to customer requirements, from small motors of only a few kilowatts up to 3 MW, and from speeds of around 100 rpm to high speed (> 25,000 rpm) motors.
