Stepper motor meets design needs

by Anna Allen, Staff Editor

Manufacturers of portable monitoring devices require a permanent-magnet stepper motor that is small in size and weight, and provides a low current level for critical power needs.

Model 15M020D1B permanent-magnet stepper motor from Thomson Airpax Mechatronics LLC meets these requirements. According to Hasit Parikh, advanced design engineer, the motor "incorporates modular, intelligent automation to ensure quality, reliability, and competitive pricing, while allowing for electrical and mechanical modifications to meet different application requirements."

The motor, which measures 15 3 15 mm and weighs 14 gm, produces more than 0.5 oz-inch pull-out torque at 200 pps, outperforming other motors in its frame sizes, claims Thomson Airpax Mechatronics LLC.

For intermittent-duty cycle applications, 0.5 oz-inch torque is available at 300 pulses per second, with a temperature rise of 75C. Other features include permanently lubricated sintered bearings and a bipolar winding configuration.

Model 15M020D1B's small size and ability to operate at low current levels makes it useful for applications where space and power demands are critical. These include computer-peripheral applications employing the USB feature; medical/laboratory fluid analyzers, pumps, and syringes; mobile fax machines; small printers; and back-up tape drives.
