AI Technical Summary
When existing permanent magnet motors add ventilation and heat dissipation structures, the air flow effect is poor, resulting in lower ventilation and heat dissipation effect.
A servo permanent magnet motor with cooling, ventilation and heat dissipation structure is designed, and a combined structure of circular air inlet, guide plate and circular baffle is adopted. The guide plate extends into the inner edge of the circular baffle, reducing the distance between the rear end plate of the wind direction and the fan blades, and enhancing the air inlet effect.
Through the setting of the guide plate, the overflow of wind is reduced, the efficiency of wind flow is improved, and the effect of ventilation and heat dissipation is enhanced.
