Evergreen EM ECM Commercial ECM Motor
Overview of the Evergreen Centimeters
Definition and Purpose: The Evergreen EM ECM is a motor designed to replace Original Equipment Manufacturer (OEM) constant torque Electronically Commutated Motor (ECM) indoor blower motors.
Targeted Replacements: It is specifically engineered to replace motors built with speed taps, such as the X 13 and similar competitor models, offering a quick and easy solution for field replacements.
Presenter: The information is presented by Mohali, the training manager for Riga Beloit.
Comparison Between Evergreen Centimeters and Evergreen EM
Application Overlap: Both the Evergreen Centimeters and the Evergreen EM cover similar indoor blower applications.
Evergreen EM Specifications: * Designed for or models.
Evergreen CM Differentiation: * Built specifically for commercial HVAC applications. * Voltage ratings include or .
Technical Specifications and Models
Motor Type: Multi-speed constant torque dual rotation motor.
Voltage and Horsepower Ratings: * Model: Available in sizes ranging from through . * Model: Available in sizes ranging from through .
Airflow Characteristics: The motor matches the constant torque airflow characteristics and efficiency of the X 13 motor.
Key Features and Installation Advantages
Factory Preprogramming: The Evergreen Centimeters comes preprogrammed from the factory to allow for immediate convenience and use.
Installation Compatibility: It is built with the same tap connections, horsepower ratings, and voltage ratings as the X 13, eliminating the need for complex wiring or system reconfiguration.
Automatic Rotation Configuration: Rotation is automatically configured by the motor. This feature eliminates the need for manual configuration with plugs, saving a step during the installation process.
Availability: Because it requires no complex programming in the field, the motor is readily available at distribution counters and is considered ideal for maintaining as truck stock.
Contractor Preference: While other X 13 replacement motors exist, the Evergreen Centimeters is noted as the preferred choice for contractors.
Commercial Applications and Retrofit Upgrades (CM Motor)
Energy Savings Retrofits: The motor serves as an effective energy savings retrofit upgrade for Permanent Split Capacitor (PSC) driven systems.
Target Systems: * Variable Air Volume () systems. * Air handlers. * Package systems that do not require on/off delays.
Control Versatility and Building Automation: The CM motor is well-suited for Building Automation Systems () or add-on control systems to improve air balancing. It supports multiple inputs, including: * speed taps. * Pulse Width Modulation (). * inputs.
Application Constraints and Exclusions
Prohibited Uses: The Evergreen CM should NOT be used for the following applications: * Replacing belt drive motors. * Replacing outdoor fan motors. * Replacing OEM ECM variable speed indoor blower motors.
Variable Speed Replacement Rule: Any variable speed ECM must be replaced with a direct factory replacement sourced from the specific manufacturer of the HVAC system in which it is used.
