Stepper Motors

Product Overview

The 2-phase stepper motors from Schneider Electric Motion USA are robust, maintenance-free motors designed for precise step-by-step movements. They are controlled by a stepper motor drive, such as MForce, to form a complete stepper motor drive system. These motors can operate at very high resolutions, depending on the stepper motor drive. Maximum power is achieved when the motor and electronics are perfectly matched.

Special Features

• Quiet: Optimized mechanical design and sine commutation with MForce drives ensure quiet operation with minimal resonance.
• Strong: Optimized internal motor geometry provides high power density.

Description

Key components of the stepper motor include:

• 1. Motor connection, flying leads
• 2. Housing with black protective coating
• 3. Axial flange with four mounting points (NEMA standards)
• 4. Smooth shaft end

The document displays images of stepper motors with MForce drives and individual motor components.

Characteristics

Product Offer

The product line includes 2-phase stepper motors in NEMA frame sizes 14, 17, 23, and 34. Key specifications like holding torque, number of full steps per revolution, step angle, and number of leads are provided in a table.

Motor Types

Various shaft versions are available, including round shafts with and without a single flat feature. The document details centering collar dimensions, flange size, length without shaft, motor connection types (4 flying leads), and optional rear shaft configurations.

A table provides detailed specifications for NEMA 14, 17, 23, and 34 motors, including phase current, holding torque (in oz-in and N-cm), rotor inertia, phase inductance, phase resistance, and weight.

Ambient Conditions

Operating ambient temperature range is -25°C to +40°C. Maximum installation height is < 1000m above sea level without power loss. Transport and storage temperature range is -25°C to +70°C. Relative humidity should be 15-85% (non-condensing). The thermal class is 130 (B).

Electrical and Mechanical Data

Detailed electrical and mechanical data are presented in tables for each NEMA frame size (14, 17, 23, 34), including stack length, phase current, holding torque, rotor inertia, phase inductance, phase resistance, and weight.

Performance

Speed-Torque Curves

Speed-torque curves are provided for various motor models, illustrating the relationship between torque and speed at different voltage levels (24 VDC, 45 VDC, 75 VDC). These curves help in selecting the appropriate motor for specific applications.

Part Numbers

References

A system for generating part numbers is explained, incorporating motor type, flange size, motor length, phase current, shaft type, and optional encoder. For example, a part number like 'M-1410-0.75-S' indicates a specific configuration.

Encoder options include single-end and differential optical encoders with various line counts. Encoder cables are also available.

Dimensions

Detailed dimensional drawings are provided for each NEMA frame size (14, 17, 23, 34) in both inches and millimeters. These drawings include overall length, mounting hole patterns, shaft dimensions, and optional rear shaft details.

Tables list the lengths for different motor configurations within each NEMA size.

Accessories

Encoders

Information on optical encoders, including their dimensions, number of signals, and line counts, is presented. Encoder cables for connecting these encoders are also detailed, with part numbers and lengths.
