Standard Linear Stepper Motors

Product catalog summary

Overview: The document outlines technical specifications and performance data for Johnson Electric's linear stepper motors, specifically the UCE, UCL, ULE, and UAL series. It covers dimensions, electrical characteristics, and operational guidelines.

Specifications:

Dimensions: Each motor model has specific diameters and lengths.
Travel and Speed: Details on travel per step and speed at 200 Hz are provided, varying by motor type.
Force: Maximum force output is influenced by winding, frequency, and required lifetime.
Temperature and Resistance: Operating and storage temperature ranges, along with thermal resistance and DIN standard classifications, are specified.

Procedures and Recommendations:

Driving against end stops requires prior approval from Saia Motors.
Minimize radial forces on the shaft to avoid reduced lifetime and performance.

Electrical and Mechanical Data:

Connection Types: Includes various connectors like Molex C-Grid III.
Protection and Mounting: Motors meet IP40 standards and can be mounted in any position.
Bearings: Ball bearings are standard across models.

Performance Charts: Performance charts display pull-in and pull-out ranges under constant voltage and chopper conditions, detailing duty cycles and maximum current per phase for 100% and 30% duty cycles.

Order References: Specific order references are provided based on configuration, magnet strength, and travel specifications.

Additional Specifications:

Unipolar and bipolar motor versions have rated voltages of 6V, 12V, and 24V with a 100% duty cycle.
Resistance at 20°C is 40Ω, 150Ω, and 610Ω for winding codes 03, 01, and 04, respectively.
Measurements are taken at 23°C, with lifetime dependent on load and ambient conditions.

Design and Dimensions: Motors feature 100 mm leads and a CT connector with 15 mm travel dimensions, designed for direct bayonet mount with 1.5 mm material thickness. Specific connectors include AMP - 173977-6 for both unipolar and bipolar configurations.

Performance Charts: Charts illustrate pull-in ranges at constant voltage and chopper conditions. For UAL1, frequencies reach up to 500 Hz with forces up to 18 N. For UAL5, frequencies reach up to 700 Hz with forces up to 35 N, and chopper conditions show resistance of 5.8 Ohms with frequencies up to 600 Hz and forces up to 40 N.

Current Specifications: Maximum current per phase varies with duty cycle: 300 mA for 100%, 360 mA for 60%, and 500 mA for 30%.
