24 bars sewing machine DC motor commutator armature hook commutator

DC Motor Commutator Introduction

The hook commutator is suitable for sewing machine motor.NIDE can offer an extensive line of quality motor commutators to meet your high volume, high performance criteria. Our motor commutators are produced on automated lines or dedicated production cells for consistent quality.

The segments of the motor commutator are usually made of copper and are separated from each other by mica insulation. The mica is cut so that it lies below the copper segments. Slots are cut in the riser on the commutator to facilitate the soldering of the ends of the coils. There are twice the number of segments on the commutator as there are slots in the laminated core for the coils.

On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils. By mechanically positioning the brushes on the commutator, an angle of displacement can be set up between the magnetic force of the field windings and the magnetic force of the rotor windings.

DC Motor Commutator Application

The hook commutator is used in speed control device motor, is particularly intended for household sewing machines and industrial sewing machines.

Our motor commutator is also suitable for hair dryer, mixer, vacuum cleaner, washing machine, source juice machine ,whisk, juicer, soymilk, and for other household appliances
