Getting started with Stepper Motor Drivers

Technical Appendix

Rotary stepper motors are available in eight sizes. They are unirotational motors that can operate in reversible direction (cw = clockwise and ccw = counter clockwise).

Wide range of standard motors with holding torque 0.2 up to 45 cNm

Diameter 13 mm up to 64 mm

Life rating of 25,000 hours

Saia rotational stepper motors are ideal for modulating, mixing or positioning applications. "read more"

Use the selection overview chart below to determine which size offers the desired performance and mechanical specifications. Please refer to the individual specification pages for complete performance and mechanical data.

Specified data for torque values is valid for:

a duty cycle of 100%, in Performance

Charts additionally for 30% (cycle time: 5 min, type URG only 1 min.)

an ambient temperature of 23 ±5¡C

a defined driver circuitry, with constant voltage supply

at rated voltage

Please refer to the individual size specification pages for product approvals. Smaller motors than diameter 28 are made from UL approved materials. Larger motors are UL/CSA approved.
