Efficient brusless dc motor and drive

Cheshire, Conn.— These 98 mm Series brushless dc motors are said to be 30% more efficient and 33% smaller than industry-standard packages. Three-phase MOSFET Pulse Width Modulation drive with surface-mount components eliminates need for external controllers. Available in 26- and 35-W outputs with lengths of 43.

Cheshire, Conn.—  These 98 mm Series brushless dc motors are said to be 30% more efficient and 33% smaller than industry-standard packages. Three-phase MOSFET Pulse Width Modulation drive with surface-mount components eliminates need for external controllers. Available in 26- and 35-W outputs with lengths of 43.5 and 48 mm respectively, these brushless motors have peak power up to 100 W, 50 encoder pulses per revolution, and operating speed of 100 to 3,000 rpm (without dynamic balancing) or up to 8,000 rpm (with dynamic balancing). www.thomsonindustries.com Thomson Industries Inc.
