Running the Wheelbarrow

As soon as the electric motor is driven into the network, the coil is properly fed and the armature is drawn against the electromagnet shell, thus gaining the spring resistance. These tablets, when free, move axially in their housings, thus moving away from the friction surfaces. This ends the braking action, allowing the engine to start freely. When the motor is disconnected from the mains, the control instantly interrupts the coil current and the electromagnet stops acting. Thus, the pressure springs push the armature toward the rear cover of the engine.

The pads, installed on the brake disc, are compacted between two friction surfaces, the armature and the cap, and brake the engine until it stops completely.

The braking system allows three connection systems, allowing slow, medium and fast braking. In slow braking, the brake coil rectifier bridge power is supplied directly from the motor terminals without any pause. In medium braking, a contact is interleaved to pause the power supply current of the rectifier bridge in the circuit. In rapid braking, the interrupt contact is inserted directly into one of the coil feed wires.
