Motion requirements & engineering challenges

What the Application Requires from the Drive System

A credible selection begins with the real operating duty. These inputs determine continuous rating, peak capability, technology choice and the level of integration required.

Suitable technologies & solution architecture

Engineer the Complete Motion System

Air-movement systems are selected from the fan curve and required operating points. Airflow, static pressure, speed control and thermal conditions determine the appropriate AC, EC or brushless motor platform.

01

Motor matched to the fan curve

AC, EC or brushless technology is selected from airflow, static pressure, speed range, continuous duty and efficiency across the actual operating points.

02

Fan and mechanical interface

Impeller inertia, direct or transmitted drive, bearings, mounting and the available enclosure are reviewed with the air-handling equipment.

03

Variable-speed control

Speed feedback, control input, current limit, communications and protection are configured around system demand and energy performance.

04

Acoustic and environmental duty

Noise, vibration, ambient temperature, cooling, ingress, contamination and extended operating life are confirmed under representative conditions.
