HiPot Testing

High-voltage cable testing, sometimes known as HiPot (High Potential), is a method of testing used to ensure adequate insulation in a myriad of applications ranging from electric motors and printed circuit boards to transformers and industrial cables. Users of this system may select dual-polarity DC and cable jacket or sheath output modes. Testing the insulation is vital in determining the safety of cables, reducing the chance of...

AC Motor Laser Shaft Alignment

Laser shaft alignment maximizes the life of bearings, seals and couplings, which saves you money. The vibrations from misalignment can cause premature wearing and failure of equipment. Vibrations also cause equipment to use more energy to work, which increases operating costs. The misalignment can further cause the final product to have a higher defect rate, further increasing the cost of production. Utilizing a... (posted by David 1 year 101 days ago.)

Advantages of a Synchronous Motor

The main function of a synchronous motor is the providing of constant speed. High-horsepower capacity synchronous motors are an efficient means of converting AC energy into work and provide power-factor correction. There are two types of synchronous motors: excited and non-excited. Excited synchronous motors require direct current supplied from a separate source such as a DC generator connected to the motor shaft.... (posted by David 1 year 140 days ago.)
