Leveraging sensorless drive and sine-wave drive technologies, Toshiba has been developing a broad array of brushless DC motor drivers ideal for applications that require low power consumption and silent operation.
Example: At 3,000 rpm, InPAC reduces supply current by approx. 10%, compared with the conventional fixed lead angle control (benchmarked by Toshiba).
Reduces the number of external components necessary for lead angle control and eliminates the need for any programming according to the changing operating states of a motor
|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|
