Description of an Auto Lead Angle Control Technology

為了優化馬達效率,儘管要根據來自霍爾傳感器的轉子位置信息來控制超前角,但必須使用實際設備來調節超前角。

即使馬達控制器/驅動器具有自動超前角控制功能,超前角也必需根據馬達常數,rpm和其他因素進行調整。因此,需要一種減輕用戶負擔的改進的控制方法。

Advantages of Intelligent Phase Control

智能相位控制可檢測馬達電流相位,並反饋信息以進行自動超前角控制。當馬達應用中帶有感測器時,霍爾信號的相位會自動調整以匹配馬達驅動電流的相位。
無論馬達的rpm,負載轉矩和電源電壓如何,都能實現高效率。智能相位控制還有助於減少調整導程角所需的外部零件數量。

Auto lead control technology realizing high efficiency with a simple configuration

Example: At 3,000 rpm, Intelligent Phase Control reduces supply current by approx. 10%, compared with the conventional fixed lead angle control (benchmarked by Toshiba).

Intelligent Phase Control

Intelligent Phase Control is Toshiba’s original motor control technology capable of saving power easily.
By automatically adjusting voltage and current phases during brushless motor operation, it eliminates
complicated adjustments with software and realizes high efficiency drive.

Simply configurable auto lead angle control

減少了超前角控制所需的外部組件數量,並且無需根據電動機的運行狀態變化進行任何編程

  Motor Efficiency Ease of Programming Support for Various Types of Motors Part Count Drawback
Fixed lead angle control Poor Poor Poor Moderate Changes in the rpm of a motor make the adjustment point shift, making it impossible to achieve optimal efficiency.
Lead angle must be adjusted for each type of motor.
Auto lead angle control using conventional technology Moderate Moderate Moderate Poor
Intelligent Phase Control Excellent Excellent Excellent Excellent -
