CHARACTERISTICS OF WEG MOTORS

Although WEG states that their motors usually comply with Design N, in many cases their typical actual torque values far exceed the minimum required by the standard. In most cases the values even exceed the minimum requirements of Design H. This means a very high speed-torque curve, bringing the following benefits:

1 ) Quick acceleration under heavy starting conditions, e.g. for piston pumps, loaded conveyers, high inertia loads, compressors with open valves, etc.

2 ) Quick responsiveness for special supplies such as those mentioned since standard motors are always readily available from stock, with price benefits and quick delivery.

3 ) The possibility of using reduced voltage starting methods, e.g. Star-Delta Starters, in normal cases, without affecting perfect load acceleration.

4 ) Due to the high value of the breakdown torque, momentary load peaks and temporary voltage drops are accepted without any sudden speed loss. This is a fundamental requirement for the performance of machines which are subjected to heavy load peaks, such as crushers, calender machines, etc.
