直流離心風機設計要素(中英對照)

  1、葉輪/Impeller

  葉輪由塑膠材料PA66,玻纖增強注模制成,材料符合 ROHS 及阻燃UL-V0級。Impeller made of plastic PA66,fiberglass reinforced. All material accord with ROHS and UL-V0

  2、電機/Motor

  外轉子直流無刷電機。轉子上安裝鐵氧體材料,轉子外殼表面電泳成黑色,材料符合 ROHS。

  External rotor brushless DC motor ,Rotor with ferrite and coated in black. All material accord with ROHS

  3、軟起動/Soft Start

  電機開始在低轉速起動,大約20秒到達全速,以防止來自電源的電流沖擊。The motor start at low speed,after 20 SEC running to full speed, to prevent current surges being drawn from the power supply

  4、速度輸出信號/Speed output signal

  風扇輸出一個與外接上拉電阻成比例的速度信號,風機每旋轉一周,這個信號包含3個脈沖輸出,信號最大幅值電壓為12V。

  The fan provides an output signal proportional to its speed with out pull up resistor. The signal comprises of 3 cycles per revolution of a squar. The maximum amplitude of the signal is 12 V

  5、速度控制/PWM input

  PWM輸入控制電壓范圍:0~10VDC, PWM控制信號頻率范圍:1~10 kHZ

  Signal voltage range: 0~10VDC

  The frequency for control signal of the fan shall be able to accept 1~10 kHZ.

  6、保護/Protection

  電機保護功能有堵轉保護、限流保護、低電壓與過電壓停止運轉功能

  This motor with locked-rotor protection, current limited,under-voltage and over-voltage lockout protection
