A variable frequency drive is an electronic device that allows you to start, stop, and control the speed of a three phase motor. It is also a motor starter as it is equipped with overload protection. Read more »
What is the difference between a 'new surplus' motor and a 'factory new' motor?
Our New Surplus electric motors and drives are new and unused overstock or discontinued items offered at lower prices and come with our 90-day warranty.
Factory New products are competitively priced and come with a manufacturers warranty.
Variable frequency drives (VFDs or inverters) now play an important part in major industry.
Within the last 10 years they have been perfected to control and vary the speed of 3 phase electric motors. They serve many purposes, besides speed control. Homeowners and hobbyist alike, who have lathes or milling machines with a 3 phase motor, usually don't have 3 phase power to operate. These VFDs (instead of using a rotary phase converter) can now be used to convert single phase power to 3 phase power. Read more »

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
