STEPPER-MOTOR DRIVE
StepNet
Drives stepper motors in networked and standalone motion-control applications; can be mounted flat to minimize height or sideways to minimize footprint; servo mode runs stepper motors 40% faster than their maximum stepping speed for servo performance at 50% of servo motor cost while eliminating stall risk; permits multi-axis motion synchronization, executes sophisticated motion profiles, and achieves micro stepping performance at 51,200 steps/revolution$290; delivery in four to six weeksCopley Controls Corp.

MINIATURE
LINEAR MOTOR
LEU series
Brushless linear motor; produces up to 26 lb (117 N) of peak force; 15- and 30-mm coil heights with 18-mm width; 35-, 65-, and 95-mm coil sizes supported by 60-, 90-, 150-, and 300-mm magnet channels; ironless-core design provides smooth motion since there are no iron winding laminations to produce cogging; suits high-precision and compact stage applications$500 to $750; stock to eight weeksAnorad/Rockwell Automation

DUAL-CHANNEL
DC-MOTOR CONTROLLER
AX2850
Microcomputer-based dual-channel dc motor controller; drives up to 120 A on each channel at up to 40 V; accepts commands from standard remote-control radio for simple robot applications or serial-port interface; both channels can be operated independently or combined to set a vehicle's direction and rotation by coordinating the motion on each side of the vehicle; motors may be operated in open- or closed-loop speed mode; extruded aluminum case serves as a heatsink for its output power stage$620 in single quantities; now availableRoboteq
