1. W22 NEMA Premium – Ball Bearings

Description

High performance with maximum energy efficiency is the goal of the new W22 electric motor. High efficiency and Low cost of Ownership throughout the entire motor lifetime have been the basis for the W22 development. A design created to maximize performance and energy savings.

New Cooling System

Designed to provide optimized air flow through all motor frames keeping low operational temperatures and assuring reliability and extended lifetime. The aerodynamic design of the fan cover optimizes effective airflow, thus minimizing losses due to the recirculation of air between fan and fan cover. The fan was designed to provide strength and reduced noise level. Motor terminal box and eyebolts are positioned on larger frames to allow better airflow. The new W22 cooling system also contributes to: Cooler bearing temperature extending relubrication intervals Lower Noise Level fulfilling the most demanding Health & Safety regulations Lower Overall Operational Temperature resulting in longer life

Terminal Box

Large internal space making connections more accessible to the user resulting in an easier cable handling and connection Terminal box can be mounted on top, left or right site of the motor using the same frame on the 447T and larger motors. Top mounting is optional on smaller frames

Exclusive Bearing Sealing System

Extends motor lifetime when operating in aggressive environments by protecting the motor against water and dust guaranteeing proper degree of protection

Frame

Motor feet are solid providing a highly resistant structure against vibration. The frame design has points that can be used as provisions for vibration sensors as a standard feature. Benefits from the new frame design: Motor temperature reduction Eyebolts positioned for easy handling in the application Provision for vibration sensors – frame and endshields with provisions 90° displaced according to maintenance technical recommendations. Easier and more reliable vibration analysis Solid feet – Enhanced reliability when operating on high vibration applications and also provide easier alignment on installation
