Estun servo motors – the difference between incremental encoders and absolute encoders
1. The working principle of incremental encoder:
The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses indicates the size of the displacement.
To describe the pouring water, the incremental encoder is like, looking for a non...

Estun Servo Motor - Introduction to Servo Motor Inertia Knowledge
1. What is "inertia matching"?
1. According to Newton's second law: "The required moment T of the feed system = the transmission inertia of the system J×angular acceleration θ angle". The acceleration θ affects the dynamic characteristics of the system, the smaller θ, the more time from the controller to the completion of the system's execution.

Estun servo – the difference between servo motor and stepper motor
First, the control accuracy is different
The step angle of the two-phase hybrid stepper motor is generally 3.6 ° and 1.8 °, and the step angle of the five-phase hybrid stepper motor is generally 0.72 ° and 0.36 °. There are also some high-performance stepper motors with smaller step angles. Such as Sitong company produced a kind of wire for slow wire ...

Estun servo motor - three-phase asynchronous motor winding short circuit fault handling method
1. Fault phenomenon:
The uneven distribution of the magnetic field of the ions, the unbalanced three-phase current aggravates the vibration and noise of the motor during operation, and the motor cannot be started when it is serious, and a large short-circuit current is generated in the short-circuit coil, which causes the coil to heat up rapidly and burn out.
2. Causes:
