Standard Rotary Stepper Motors

Product catalog summary

Overview: This document provides comprehensive technical specifications and performance data for various stepper motors produced by Saia Motors, including the UAG3/4, UBB, UBD, UCB, UCD, UFB, UFD, URG, and UPJ series. These motors are designed for applications requiring precise control of rotational movement and are characterized by features such as self-lubricating bearings and compliance with electric strength standards.

Specifications:

UAG3/4 Motors: Diameter of 20mm, step angle of 18°, holding torque of 5.6/4.2 mNm, and detent torque >0.6 mNm. Operates in temperatures from -20°C to +60°C. Rated voltage is 12V.
UBB Motors: Diameter of 36mm, step angle of 15°, holding torque from 1.0 to 1.9 cNm. Operates in temperatures from -15°C to +55°C. Rated voltages are 3V, 6V, 12V, and 24V.
UBD, UCB, UCD Series: Step angles of 7.5° or 15°, holding torque ranging from 1.3 to 2.7 cNm. Available in bipolar and unipolar configurations.
UPJ Series: Step angle of 11.25°, holding torque of 30 cNm (UPJ1) and 45 cNm (UPJ5). Rated voltage is 4.5 V.

Performance:

Performance charts illustrate pull-in and pull-out ranges at different frequencies and duty cycles for UAG3/4 and UBB motors.
UPJ series performance charts show operating torque plotted against frequency for different configurations.

Additional Features:

All motors feature self-lubricating sintered bronze bearings and are protected to IP30 or IP40 standards.
Motors can be mounted in any position and are equipped with electrical connection cables or lead wires.
Thermal resistance and class ratings ensure efficient operation within specified temperature ranges.

Environmental and Approval Standards:

Compliant with DIN EN 60034-1 and DIN EN 60335-1 standards.
Climatic class according to DIN IEC 60721-2-1.
Thermal class B according to DIN EN 60085, with Class A available on request.

Recommendations:

Ensure proper mounting and electrical connections to maintain motor performance and longevity.
Consider thermal resistance and ambient temperature ranges when selecting a motor for specific applications.
Additional protection may be necessary for applications requiring specific insulation standards.
