Here is the trending technology that three motor manufacturers are saying will improve the future of motors in HVAC.

The business employs around 600 people and generated revenues of approximately $63 million in 2021.

PSC motors can be referred to as constant speed motors; X13 ECMs can be referred to as constant torque motors; and ECM 2.3 variable-speed motors can be referred to as constant airflow motors.

Beginning July 3, 2019, the Department of Energy is requiring a maximum fan energy rating (FER) for furnace fans.

HVAC industry members are debating how the DOE’s new rules — the first-ever for commercial and industrial fans — will impact their operations.

Unico Inc. announced it is making highly efficient EC motors standard for all blower models within its modular air handling units.

The speedway’s original HVAC equipment, installed nearly 30 years ago, was outdated, and with one HVAC unit per suite, the cost to run and maintain the equipment was significant.

Troubleshooting PSC fan motors is a common task for service technicians, and failures tend to be either electrical or mechanical.
