Three-Phase: W22 Crusher Duty TEFC (IP55)

Description

WEG Crusher Duty W22 motors are specifically designed to meet the demanding requirements of the rock crushing industry. FC-200 grade cast iron, provides superior strength and heat dissipation. And 4140 high-strength steel shafts keep the motor running when others fail. These motors are designed for vertical or horizontal mounting and have exceptional high starting and breakdown torque.
High performance with maximum energy efficiency is the goal of the WEG W22 Crusher Duty 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.
Compare the standard features of the WEG W22 Crusher Duty motor to any other and see why these motors are “Crusher Duty” tough!

Terminal Box

Increased 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 side of the motor using the same frame on the 445/7T and larger motors.

Cooling System

Designed to provide improved air flow through all motor frames keeping low operational temperatures and assuring reliability and extended lifetime. The aerodynamic design of the fan cover increases 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 were repositioned on larger frames to allow better airflow.
The 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

Frame

Motor feet are solid providing a more 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 frame design:

• Motor temperature reduction
• Eyebolts repositioned – easier 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
