August 2006 Equipment Roundup - Motors and Drives

Motors and drives may be smaller in size and cost than the machines that do the actual "processing" work in a food processing plant, but their smooth functioning is just as critical to plant operations.

Handle harsh environments

The BSM series of servo motors are available in stainless steel for harsh environments, as well as for food and pharmaceutical applications. They feature popular shaft/mounting dimensions, high-voltage insulation, high continuous rated operating temperature plus an over-temperature protection thermal switch, standard windings for 160, 300 and 600 bus volts (custom windings available) and choice of feedback options: resolver, encoder, EnDat and SSI. The N series (low inertia) torque range is 0.45 Nm to 40 Nm, and the C series (high inertia) ranges from 0.45 Nm to 30 Nm.

Simple and economical

The new Simple Economy (SE1) and Simple Wireless (SW1) S series of Micro AC Drives are simple to install, economical to use, compact and reliable. They are ideal for basic industrial applications. The two drives share a common set of parameters, the first 13 of which meet 80 percent of users’ most common needs making start-up for both drives fast and easy. Another 26 parameters are available for additional functionality and flexibility.

Advanced AC drive

Dual microprocessors and motor control algorithms provide superior torque performance and speed regulation in the new Telemecanique Altivar variable speed AC drive. Advanced materials reduce the size by 15 percent compared to previous generations. These features make it the most advanced AC drive on the market for constant torque applications, the manufacturer claims. The design is operator friendly and the drive is highly expandable making it suitable for material handling, packaging, hoisting and a wide range of food processing applications.

Efficient drive invertors

A new generation of drive invertors, the Movidrive B universal motor controller, offers more basic functions, extended lower speed range and increased overload capacity over the company’s previous design. The new inverters offer performance and control quality levels for AC asynchronous motors previously only possible with servo drives or DC motors. Available in two versions, they offer unprecedented efficiency levels during startup, operation and application.
