A new type of the electronic detector of rotor position and speed
新型的电子式转子位置检测和测速装置
The equipment of " double light harrier " was developed and applied to measure object ' s velocity , which improved the precision of measuring impacting velocity
作者提出并完成研制的“双挡光片法”测速装置，成功地解决了冲击速度的精确测定问题。
In direct torque control system , speed sensors are usually used to survey the speed of motor , but speed sensors have many disadvantages , such as inconvenient fixing and maintenance , inaccurate precision . at present it is an efficient and feasible method to estimate speed by using software instead of hardware
以往在直接转矩控制系统中采用速度传感器检测速度信号，由于测速装置具有安装不便、维修困难、测量精度差等缺点，因而采用软件代替硬件检测设备辨识速度，即进行无速度传感器的设计，不失为一种有效可行的速度辨识方法。
