Normalized Conjugate Categories and Values October 31, 2017

Depending on the characteristics and properties of the gearbox in relation to the starting speed and current, three-phase induction motors with cage rotors can be classified into different categories, each of which must be appropriate to a specific type of load. These categories are defined by official standards. Category H is a high starting torque with normal starting current and low slip. It is used for loads that need larger torque at start, such as sieves and loader conveyors. Category D consists of the high starting torque, with normal starting current and high slip.

It is used in eccentric presses and similar machines baldor CSPM3558T, in which the load presents periodic peaks. Also used in elevators and loads requiring very high starting torque and limited starting current. The NY category includes motors similar to Category N, intended for star-triangle startup. The category HY includes the engines similar to those of category H, however, foreseen for start star-triangle. Category N consists of the normal starting conjugate, normal starting current, with low slip. They integrate most of the motors found in the market and lend themselves to the activation of normal loads, such as pumps and machine tools.
