International. Rosenberg's new "Generation 3" EC engine has been selected as a finalist in the AHR 2020 Innovation Awards competition. The new fan motors are used to drive axial fans and curved impellers backwards in environments where power, reliability and control are critical.
Part of Rosenberg's innovation is the technology that allows 40% more motor winding density, resulting in a 20-30% increase in power in the same space. They are also sophisticated integrated electronic components for communication, control and increased reliability. The new motors are 100% speed controllable and are CE, UL-R and RoHS approved.
Advances include:
- Three-phase supply from 200 to 480 VAC. Previous generations of EC engines were designed for an input power of 200-230 VAC or 380-480 VAC that required manufacturers to inventory both. The new engine automatically adjusts to the actual input power over the entire range, allowing for reduced inventory cost.
- Power supply from 280 to 680 VDC. The motor automatically adjusts from AC input voltage to DC when required in data centers or battery backup applications.
- Integrated inspection LED showing the status of the motors and the operating status of Modbus.
- ModBus RTU functionality. The motor monitors its current power consumption and records the total energy consumption, load profile and fan operating temperature over time. This simplifies performance optimization and preventive maintenance.
- Electronic rapid change technology (EQC). The electronic motor head can be replaced in minutes without touching other parts of the fan.
- IT network (grounding system) support for increased system fault tolerance, especially for hospitals and data centers.
- Higher power output: The previous engine generation offered 3.5kW of power. Thanks to significant investments in our motor winding technology, Rosenberg motors now offer a power output of 4.7 kW (33% more) under the same footprint.
