MOTOR LINE EXPANSION

Standard- and low-inertia models

Baldor Electric Co. has expanded its line of servo motors to include inertial matching for machines. Delivery can now be same-day since the expansion includes encoders. Encoders added to the stock feature a 2,500 ppr encoder as a standard. The expansion also contains BSM servomotors with holding brakes. Typical applications for the newly updated BSM-series include packaging, material handling, registration, labeling, flying shears, capping, form/fill/seal, and factory automation.

MICROSTEPPING DRIVES

No need for cable

The four-axis SDM-20640 amplifier board designed for microstepping four stepper motors attaches directly to the 96-pin DIN connector of the controller without any need for a cable. The board is a compact 6.92 × 5.10 inches and each amplifier is able to drive a two-phase bipolar stepper motor operating at 18 to 60V dc at up to 3.5A. There are four featured settings for the board: 0.5, 1, 2, and 3.5A. Along with current settings, the board has a low-current mode that reduces current power by 75 percent when the motor is at a stop. The drives produce 12,800 steps per revolution for a standard 200-step motor. Galil Motion Control Inc.http://rbi.ims.ca/3855-631

INTEGRATED DRIVE FOR MOTOR

For simplified motor control

A new integrated drive has been added to the NEMA size 23 brushless dc motor, which can be customized according to specific application requirements. The drive controls the motor speed by analog voltage or pulse width modulation and is compact, adding 1 inch to the motor length. The standard drive is rated at 24V dc but can be configured for voltages up to 48V dc. The command lead, configurable to accept either a 0-6V dc signal or a 6V, 1 KHz pulse with modulated square wave, controls motor speed. EAD Motorshttp://rbi.ims.ca/3855-632
