Gearmotor.

This manufacturer has added 1/2-hp parallel shaft gearmotors, suitable for use with inverter drives, to their product line. The line additions have reversible, variable-speed 3-phase motors, and operate at 230 VAC, 50/60 Hz. They are offered in two different gearcase styles: 2-stage units in the 650 gearcase, and 2- or 3-stage units in the 485 gearcase. They may also be mounted in any position. All three of the new models offer extended life expectancy in continuous duty applications. Speed ratings range from 2.9 to 29.1 rpm @ 6 Hz, and 44.4 to 436.5 rpm @ 90 Hz. Auxiliary cooling is not required for low frequency operation. Bison Gear and Engineering, 3850 Ohio Ave, St Charles, IL 60174.

Servo motor software. Cymex software simplifies servo system design and analysis, allowing engineers to more accurately design systems in less time and at a lower cost. The software contains a database of nearly 1,400 servomotors from a wide variety of manufacturers, plus users can add in different motors including stepper, DC, reluctance, or induction motors to the database.

Servo drives. This line of compact servo drives offers a good ratio of cost to performance to size. They are designed for industrial, medical, and process control automation. They provide ideal solutions for incremental motion control, velocity loop, and positioning systems. The drives can be used in three velocity modes and operate with single voltage inputs from 20 to 275 VDC.

Medical motor. The size 11 Medical Motor is designed specifically for use with mechanical manipulators used on neurosurgery applications. They weigh 0.2 lbs. and feature a 1.1-in. diameter for performance where space is limited. Size 11 medical motors are designed to be sterilized with alcohol, and can be easily assembled by technicians wearing rubber gloves in a sterile environment.

Rugged servomotor. The BV series of fluid power servomotors has been developed for hostile and aggressive environments, particularly under water. All external components are individually nickel plated with a watertight, stainless-steel electrical connector for the encoder. It weighs less than 20 lbs. and delivers up to 15 hp. These motors are capable of smooth operation at 1 rpm, and are available in various sizes and styles.

Indexing servo systems. This addition to the existing PV family of servo systems includes a built-in indexer and a DeviceNet interface. It connects up to 64 PV indexing servo systems to a DeviceNet master. The need for a separate indexer card in the PLC or PC is elminated. The compact size PV drives include 15 and 30 amp ratings with common height and depth dimensions. Sanyo Denki America, 468 Amapola Ave, Torrance, CA 90501. 310-783-5400. http://www.sanyodenki.com
