AC motors
The drive using an external rotor motor offers space-saving, compact and attractive design. The engine sits inside the impeller and is thus optimally cooled. For this reason, a 100%variable speed control can be guaranteed. V-belts, additional tension bars and motor mounting devices are not necessary. Only well-dimensioned ball-bearings, fitted on both sides and long-life lubricants are used. Both ball-bearing seats are ground to high precision in one work process to eliminate any vibration.
External rotor motors are also characterised by an extremely low start-up current. The drive motors correspond primarily to protection class IP54 according to DIN EN 60034-5. The winding insulation corresponds to the thermal class F. In addition, the winding has a standard moisture protection impregnation.
EC motors
The EC motors used are characterised by very high efficiency even at partial loads, and excellent control behaviour. They are easy to connect, individually preconfigured, compact in design and have a high power density. The implementation of additional functions (e.g. volumetric flow and pressure control) is possible. Rosenberg EC motors primarily meet protection class IP54; input voltage of 380V-480V (50/60Hz). Rosenberg EC motors are continuous speed controllable and have integrated motor protection.
