HEINZMANN gearing up for demanding applications in motor control

Press article HEINZMANN (november, 2010)

As a logical progression to the successful development and production of brushless disc-type motors,HEINZMANN has now set itself the task of offering its motors with their own control, integrated into the motor housing. HEINZMANN is looking to offer a solution that convinces in terms of both technology and cost efficiency,not just for the motor itself, but for its control. Its objective is therefore to turn the motor into a complete drive system, independent from external controllers.

This endeavour also gives HEINZMANN the opportunity to individually optimise all the specific features of its range of disctype motors in a logically consistent manner. The company’s own inverter can be tailored to the specific characteristics and functionalities of the different customer applications, enabling efficiency to be increased still further. This opens the door to an even greater number of applications for these drives.

Unnecessary interfaces and functions are being deliberately dispensed with. It is more the idea of providing the user with a fully customised and perfectly tailored drive system, that is to say with a “Connect and forget” concept.

Furthermore, the integration of a controller into the motor housing brings a noticeable advantage in expenditure, as savings are made in terms of space and connectors, and the wiring is reduced to the minimum. So, the user benefits in two ways: from a lean and low-priced overall system from a single source. The motor/inverter combination shown in figure 1 is based on the flat disc-type motor “SL-EC120 11B”. It is directly connected to the 3-phase 400 V low-voltage network and supplies up to 500 W in S1 operation. The nominal speeds can be designed according to customer specifications (1500 - 3000 rpm). In doing so, it is possible to operate the inverter in both torque and speed control. Pumps and fans are the most obvious candidates for complete integration.
