Welcome to Oriental Motor's "Engineering Notes" Blog:

In this post, we will explain how the two drive systems, square wave drive and sine wave drive, can affect motor torque performance.

There is a close relationship between the drive system and brushless motor characteristics, and various methods have been used to improve the controllability and characteristics of motors.  In this post, we will explain two typical drive systems: square wave drive and sine wave drive.

The BLV Series is one of two DC-input brushless motor speed control systems we offer.  While a brushless motor with hall-effect sensor feedback provides constant torque, wide speed range, and speed regulation, the BLV driver offers unique functions designed for mobile robots, such as low battery operation and ramp operation.

The viscosity change in liquids can vary the torque required for mixing.  For AC asynchronous motors such as AC induction motors, the rated speed is affected by load torque fluctuations, which may cause inconsistency in the final product.  Is there a better motor for the job?
