An important specification of the induction motors that needs to be highlighted consists of its nameplate, which presents information of extreme importance as the CV, which is the mechanical power of the electric motor in cv. It refers to the power the motor offers, within its nominal assignments. Already Ip / In consists of the relation between the starting and nominal currents. In order to avoid high starting currents, there are many ways to carry out the electric machine drives that allow a drop in the starting current value of some machines, such as the parallel-series start, the self-aligning start and the star- triangle.
Hz is the frequency of the motor Baldor BC142-SIH operating voltage. The acronym RPM refers directly to the motor speed at the rated operating frequency. Induction motors may vary having three, six, nine or twelve outer terminals. In the case of the six-terminal motor are found two types of connection, the triangle with the nominal winding of the phase winding equal to 220 V and the star with a star-connected winding the line voltage can be up to three times the winding voltage.
