Infinitum EC+ Update Puts Integrated Motor Control on Buyer Radar

Industry Update

Control.com reported that Infinitum has introduced the Aircore EC+, an updated electronically commutated motor aimed at improving efficiency, reliability and speed control in HVAC fan and pump applications. The article says the package uses Infinitum's printed-circuit-board stator technology and integrated electronics, positioning the motor as an alternative to conventional motor and external drive combinations in selected applications.

According to the report, the Aircore EC+ includes integrated active front-end electronics intended to reduce harmonic distortion, plus hybrid ceramic bearings and an IP65 enclosure for harsh or outdoor operating conditions. The article also notes high-resistance grounding and says the motor is offered in four frame sizes, with power ratings from 1 HP to 15 HP and voltage options including 460, 415 and 575 volts.

For motor buyers, the practical update is not only the motor itself but the system boundary. When motor control electronics, harmonic mitigation and enclosure protection are built into the motor package, procurement teams need to compare the full installed package against separate motors, drives, filters, cabinet space and field wiring.

Buyer Considerations

Buyers evaluating EC motors for fans or pumps should confirm the required frame size, horsepower, voltage, speed range, mounting dimensions and environmental rating against the machine or facility specification. The Control.com report says active front-end technology is available on selected larger frame sizes, so teams should verify which configurations include the feature before assuming it applies across the full range.

The update also changes the questions engineers should ask during supplier comparison. An integrated EC motor package may reduce the need for a separate variable-frequency drive in some designs, but buyers still need to check protection coordination, service access, spare-part strategy, communication requirements, thermal conditions and compatibility with existing control panels.

For applications where harmonic distortion, nuisance trips or outdoor exposure have caused operating issues, the reported features give buyers a clear checklist for evaluation. They should request application-specific documentation from the manufacturer or distributor before changing a qualified motor, pump or fan assembly.

Frequently Asked Questions

What type of motor is discussed in this update?

The update concerns Infinitum's Aircore EC+, an electronically commutated motor with integrated electronics for HVAC fan and pump applications.

Does the update remove the need for a separate drive in every installation?

Not necessarily. The report describes integrated motor control electronics, but buyers should confirm application requirements, control architecture and available configurations before removing a separate drive from a design.

Which buyer checks are most important before specifying this kind of motor?

Buyers should verify frame size, horsepower, voltage, speed range, enclosure rating, harmonic requirements, bearing suitability, service access and whether the required active front-end feature is included in the selected configuration.
