This introduction provides a comprehensive overview of the MSK100D-0300-NN-S1-BG2-NNNN motor, highlighting its key features, application scenarios, and technical parameters.

The control accuracy of the AC servo motor is guaranteed by the rotary encoder at the rear end of the motor shaft.

Taking the Panasonic full digital AC servo motor as an example, for the motor with a standard 2500-line encoder,

since the four-time frequency technology is used inside the driver, its pulse equivalent is 360°/10000=0.036°. For the

motor with a 17-bit encoder, the driver rotates one circle for each 217=131072 received pulses, that is, its pulse equivalent

is 360°/131072=9.89 seconds. It is 1/655 of the pulse equivalent of the stepping motor with a step angle of 1.8°.

Two, different low frequency characteristics

Stepper motors are prone to low-frequency vibration at low speeds. The vibration frequency is related to the load condition

and the performance of the driver, and it is generally believed that the vibration frequency is

half of the motor”s no-load starting frequency. This low-frequency vibration phenomenon, determined

by the working principle of the stepper motor, is very disadvantageous to the normal operation of the machine.

When the stepper motor operates at low speed, it is generally necessary to use damping technology to overcome

the low-frequency vibration phenomenon, such as adding a damper to the motor or using the microstepping technology on the driver, etc.
