<p>The coupling between frequency converter 21 and electric motor 1 is intended to produce greater precision of regulation, a smaller footprint, lower cost of installation, and eliminate perturbations; the converter, contained in a cylindrical structure 21, for example, has heat dissipating fins 28 and a terminal block N, connected to the terminal block M of the motor via cable 27; a cylindrical collar 22, having slotted holes 23, encloses the zone of connection between motor 1 and converter 21; it is used to vary the power supply frequency of the electric motor at industrial installations.</p> |
