In the precision world of micro motors, stable, efficient, and long-lasting operation is the ultimate goal. The key internal battle that determines this performance is fought in a tiny space—the "commutation" process, where the current direction in the armature winding switches. As a professional micro motor manufacturer, Lihua Motor understands deeply: superior commutation performance is the soul of a high-end micro motor.
Commutation: The Precise "Conductor" Inside a Micro Motor
During operation, a DC micro motor's rotating armature winding must continuously switch current direction via the brushes and commutator to maintain continuous rotation. The smoothness of this process is directly reflected in the size of the spark between the brush and commutator. According to stringent standards, the commutation spark of a quality micro motor must be controlled at a very low level (e.g., Grade 1 or 5/4). This is the physical foundation for achieving low noise, low EMI, long lifespan, and high reliability.
Lihua Motor's Philosophy of Commutation System Integration
We are not just assemblers; we are system integration experts. For the core commutation process, we exercise full-chain control from design inception to final testing:
Electromagnetic Design Optimization: Through advanced magnetic field simulation, we meticulously design the winding and commutator layout to minimize commutation EMF at the source, achieving near-ideal linear commutation and maximizing the suppression of sparks from electromagnetic causes.
Precision Mechanical Synergy: We know that even the best electromagnetic design requires perfect mechanical cooperation. Lihua Motor strictly controls:
Commutator Roundness and Surface Finish: Ensures smooth contact.
Precise Brush Selection and Matching: Includes material, pressure, and curvature compatibility with the commutator.
Dynamic Balance and Concentricity: Guarantees absolute stability of the commutation system during high-speed operation.
Rigorous Processes and Testing: From commutator sintering and dynamic balance correction to full motor commutation spark tests and life aging tests, every step ensures long-term commutation stability.
