Low Voltage NEMA Motors

Product catalog summary
Introduction
This document is a comprehensive catalog for Low Voltage NEMA Motors, focusing on horizontal and vertical induction motors. It covers motor types such as GP, SD, XP, and DP, providing detailed information on selection, pricing, and technical specifications.
NEMA Premium Certification
Motors with the NEMA Premium label adhere to higher efficiency standards. Manufacturers must submit efficiency test data to the US Department of Energy and undergo third-party testing to verify efficiency claims.
Wide Selection of Motors
ABB offers a broad range of motors with power ratings from 1HP to 800HP and voltages up to 600V. The company provides modification and custom options to meet specific project needs.
Energy Efficiency
The US Department of Energy's rule effective June 1, 2016, requires most 3-phase industrial motors to meet NEMA Premium efficiency standards, covering a broader range of motor types than previous legislation.
Warranty and Support
ABB provides a warranty for its motors, covering defects in workmanship and material for up to five years, depending on the motor type. The warranty excludes service calls or overtime.
Cancellation Charges and Change Notices
Cancellation charges apply to modified or custom motors, with a minimum charge of $100. Stock motors can be returned with a restocking fee if in new condition. Change notices for in-process orders incur a $100 charge plus modification costs.
Technical Tables and Drawings
The catalog includes technical tables and drawings for detailed specifications and dimensions of the motors.
Technical Details
MLFB Structure – Option Codes: The MLFB structure outlines the coding system for motor series, types, and configurations, including codes for standard GP, SD motors, definite purpose motors, and next-generation NEMA motors.
Voltage and Connection: Low voltage NEMA motors operate between 200-600V. Special windings like Part-Winding-Start and Wye-Start/Delta-Run help limit inrush current. Voltage tolerance is +/-10% and frequency tolerance is +/-5% as per NEMA MG-1 standards.
Mounting: Motors can be foot-mounted or flange-mounted in various configurations (horizontal, vertical, wall, or ceiling). Flange mounting allows direct coupling to equipment, and C-face and D-flange options are available.
Winding Protection: Various protection options include PTC thermistors, thermostats, and RTDs. Insulation systems are compliant with NEMA MG-1, with Class F and Class H insulation available for different frame sizes. Additional protection against moisture and fungus is provided through processes like Vacuum Pressure Impregnation (VPI).
Motor Selection and Pricing
Severe Duty Low Voltage NEMA Motors: Includes models like SD200 and SD200 841, designed for harsh environments with specific pricing structures.
Definite Purpose Low Voltage NEMA Motors: Includes the DP200 HPS model, tailored for specific applications with unique pricing.
Option Selection and Pricing: Introduces the process for selecting and pricing additional motor options, ensuring customization for specific needs.
Terminal Boxes and Leads
Various configurations for terminal boxes are available, including different mounting positions and orientations. Standard terminal leads are Class H insulated with ring terminals, and options for special cable lengths are provided. Main terminal boxes are cast iron with a gasket and can be modified for dual entry or non-standard NPT entries.
Auxiliary Terminal Boxes
Auxiliary boxes are available for additional accessories and can be attached to the motor frame or main terminal box. Options include cast iron or aluminum condulet boxes, with specific configurations for thermal protection and space heaters.
Bearings and Lubrication
Standard bearings are re-greaseable with a long lifespan, and various options for bearing insulation and hybrid ceramic bearings are available to prevent shaft currents. Lubrication options include standard EXXONMOBIL POLYREX EM grease, with alternatives like MOBIL 28 and MOBILITH SCH 100 for specific conditions. Oil mist provisions are available for severe duty motors.
Thermal Protection
Stator and bearing RTDs are available for temperature monitoring, with specific configurations for installation and auxiliary box requirements.
Overhung Load/Belted Considerations
Recommendations for roller bearings on the drive end for overhung load applications are provided, along with criteria for belting evaluations.
VFD Application Considerations
Insulated bearings are recommended for larger frames to prevent damage from shaft currents caused by VFD supply. Hybrid ceramic bearings are suggested to eliminate currents passing through the bearings.
Specifications and Features:
The document discusses various features and specifications of NEMA motors, including the DYNAPAR SLIM Tach ST85 encoder, which is a c-face mounted 1024 PPR encoder with single output. It also mentions the option for additional cooling in VFD applications through external force cooling, which can be added to severe duty motors.
Standards:
IEEE 841 features are applicable to frame size 500 motors, adding specific features to the motor. Motors over 500 HP are labeled with "IEEE 841 Features."
Balance:
SD200 motors up to L449 frame are dynamically balanced to commercial limits, with precision and extra precision balance options available.
Paint and Packaging:
The document outlines various paint systems and packaging options for NEMA motors. Standard paint provides corrosion protection, with special paint systems available for higher corrosive environments. Packaging options include stackable crates and export packaging with additional protection features.
Documentation:
ABB offers a range of documentation and certificates, available for download through their online configurator tool. Documentation includes nameplates, certificates of compliance, performance curves, and various technical drawings.
Tests:
The document details various tests conducted on the motors, including routine tests, noise tests, and complete tests, all in accordance with IEEE and NEMA standards. Test reports provide detailed information on motor performance and compliance.
Conclusion:
The document provides comprehensive information on the specifications, standards, and testing of NEMA motors, highlighting the customization options available for different applications and environments.
