What is a stainless steel ball screw commutator?

Stainless steel ball screw commutatorThe commutator is composed of a set of contact rods fixed on the rotating shaft of the machine and connected to the armature winding; When the shaft rotates, the commutator reverses the flow of current in the winding. For a single armature winding, when the shaft has completed a semi complete turn, the winding is now connected, allowing the current to pass through it in the opposite direction to the initial direction.

How to use stainless steel ball screw commutator?

At least three contact pieces are required to form a simple commutator, preventing the phenomenon of "dead" commutator. There are only two commutator pieces when two brushes bridge at the same time. The brush is wider than the insulation gap to ensure that the brush is always in contact with the armature coil. The commutator has at least three segments, although the rotor may stop at one position and the two commutator segments make contact with one brush, the weapon of only one rotor will still be correct. With the remaining rotating arms, the motor can generate sufficient torque, the rotor begins to rotate, and the generator can provide power to the external circuit.

What are the advantages of stainless steel ball screw commutators?

The efficiency of the commutator is relatively low and requires regular maintenance, such as bristle replacement. Therefore, the use of transfer machines is decreasing and being replaced by alternating current (AC) machines. In recent years, brushless DC motors have been used with switches on pipeline switches.In a motor, the armature current causes a fixed magnetic field to generate rotational force, or rotates on the coil to make it rotate; In a generator, the mechanical torque applied to the shaft maintains the movement of the armature winding through a fixed magnetic field, thereby generating current in the coil. Shandong Jingrui Automation Equipment Co., Ltd. operates in both motor and generator scenarios-Mobile robot manufacturer, handling robotic arm,Palletizing robot production factoryIt was found that the commutator periodically reverses the current flow through the coil, causing the current to continue in only one direction outside the circuit.
