Three Phase Wheel Drive Operation

The three-phase brake motor consists of an induction motor coupled to a single-disc brake, forming a robust and compact integral unit. The induction motor is fully enclosed and features external ventilation, with the same performance characteristics and sturdiness of the engine line. The brake motor is usually found in graphic machines, adjustment of rolling mill rollers, elevators, cranes, cranes, folding machines, winding machines, washing and bottling machines, packing machines and looms, among others.

The drive coil of the electromagnet is managed by a continuous current, generated by a bridge rectifier that counts on silicon diodes and varistors, that avoid peaks of tension, leaving that an interruption of the current takes place. The DC power supply allows more agility and uniformity of brake actuation. The brake is formed by few moving parts, which guarantee a long life with almost no maintenance.

The double face of pellets forms a large surface of friction, which causes a reduced pressure on them, reduced heating and almost no wear. The brake is cooled by proper engine ventilation. The electromagnet drive coil, protected with epoxy resin, acts continuously with voltages of 10% below or above nominal.
