Classes of Motor Duty in Electrical Drives: IS: 4722-1968 categorises various load time variations encountered in practice into eight standard Classes of Motor Duty in Electrical Drives: Continuous duty. Short…
Selection of Motor Power Rating: The Selection of Motor Power Rating of a motor for a specific application must be carefully chosen to achieve economy with reliability. Use of a…
Closed Loop Speed Control of Multi Motor Drives: When mechanical part of the load is of large physical dimension it becomes desirable to share the load between several motors. For…
Motor Design Parameters: Different parts of a load may be coupled through different mechanisms, such as gears, V-belts and crankshaft. These parts may have different speeds and different types of…
Four Quadrant Operation of Motor Drive: For consideration of Four Quadrant Operation of Motor Drive, it is useful to establish suitable conventions about the signs of torque and speed. Motor…
Torque Equation of Motor Load System: A motor generally drives a load (machine) through some transmission system. While motor always rotates, the load may rotate or may undergo a translational…
