Electric Motor Datasheet

Aircore EC
IES150 5HP 1800RPM

Integrated motor & drive

Infinitum’s electric motor with integrated VFD facilitates variable speed applications, reducing overall energy usage by running the motor at lower speeds when possible.

Aircore EC efficiency

The copper-etched PCB stator design increases efficiency by 10 to 15 percent by eliminating high-loss eddy currents and improved fan-to-motor mounting proximity.

Key Benefits

Short lead times
Available for immediate shipping.
Our simplified electric motor design and PCB stator technology can be rapidly manufactured with exact, reliable specifications.

Superior control
The integrated variable frequency drive (VFD) facilitates variable speed applications, reducing overall energy usage by running the motor at lower speeds when possible.

Software enabled
Our programmable software provides direct control over operational perimeters providing maximum performance for the lifetime of the motor, allowing you to create customized sequences for application-specific functionality. The built-in connectivity improves reliability from real-time data monitoring of critical equipment.

Small and powerful
Our lightweight durable materials generate the same amount of power as a traditional iron core motor in a package that is 50% lighter and smaller. The PCB stator maximizes power density by combining low-volume, high-energy product magnets and direct coil cooling, providing two to three times the current density of a conventional motor.

Cooling towers

Easy to install

Aircore EC motors are smaller and lighter than traditional iron core motors, making it possible to directly mount the motor on applications — Resulting in smaller systems with increased efficiency that saves space, reduce wiring costs, and shorten commissioning time.

Easy to maintain

Optional IoT connectivity makes predictive and prescriptive maintenance possible by collecting and analyzing data to provide real-time, actionable insights. In the event a component needs replacing, the modular design facilitates replacing just that part rather than the entire motor.

A motor to last a lifetime

With negligible bearing current, Infinitum electric motor systems are much less likely to fail, and only parts that fail need to be replaced. With our circular design strategy, the majority of components can be reused and kept in service for over 100 years.

Power, intelligence and controls all in one

We designed our VFD and motor to meet the thermal performance of various load conditions. Our integrated VFD continuously monitors voltage, currents, and the temperature of electronic circuits. The VFD is specifically tuned to the motor — matched for stress and load conditions, with fewer opportunities for failure.

Real-time IoT operational monitoring

The optional IoT module provides static and real-time operational information. This IoT module utilizes an FCC-certified Digi Xbee® 3 hardware platform, communicating cloud-based applications via a cellular (4 G LTE-M) transceiver. End-to-end encryption, authentication and integrity are provided via the Digi module.
