In San Bernardino, California, MacroAir Technologies designs and manufactures air circulation products. One of MacroAir's latest innovations, the six-blade high volume low speed (HVLS) industrial fan outperforms the company's own highly successful ten-blade fan series by requiring 40% less aluminum and 13% less power in its manufacture and it weighs in at 30% less. "We chose motors with carefully matched gear reducers to provide efficiency, reliability, long life and low noise,&quo …

Do you know how to maintain variable frequency drives (VFDs)? Doing so is easier than you might think. By integrating some simple, logical steps into your preventative maintenance program, you can ensure your drives provide many years of trouble-free service. Before looking at those steps, let's quickly review what a Lenze VFD is and how it works. A Quick Overview A Lenze AC Tech VFD Controls the speed, torque and direction of an AC Induction motor.

Improving The Mix Meanwhile, Baginto AB bakery in Sweden has been able to upgrade its mixing and dough preparation equipment, improving productivity and flexibility with Lenze SMD and SMVector IP65 Inverter Drives. The highly compact SMD drives are ideal for retrofitting in existing panels at the bakery, whilst the IP65 rating of the SMVector drives enables them to be mounted directly to stainless steel surfaces without the cost and complexity of control cabinets. In addition wiring is greatly …

You can divide the world of electronic motor drives into two categories: AC and DC. A motor drive controls the speed, torque, direction and resulting horsepower of a motor. A DC drive typically controls a shunt wound DC motor, which has separate armature and field circuits. AC drives control AC induction motors, and-like their DC counterparts-control speed, torque, and horsepower. Application As An Example Let's take a brief look at a drive application. In Figure 1, you can see a simple ap …

A B Graphic International (ABG), a global manufacturer of label converting and finishing equipment, has set a new standard with the latest generation of their machines.
