Optical Encoders in Brushless Servo Motors

The trend towards wide scale use of Brushless Motors is being driven by manufacturing cost reductions, improved efficiencies, greater reliability, availability of improved drive electronics, and the availability of improved sensors for motor control. The brushless motors, independently whether they

Notes on encoder resolution for velocity control of motors

The simplest velocity estimation method is the Euler approximation that takes the difference of two sampling positions divided by the sampling period. Typically the position measurements are taken with encoders or resolvers which contain stochastic errors which result in enormous
