Incremental Encoder Motor

Zkseasy defines incremental encoder motors specifically designed to be compatible with incremental 2500-line magnetic encoders and 2048-line optical encoders. These motors reflect the rotation of the motor through progressively increasing angular pulses in their signal output. They memorize relative position information and require zero-position calibration each time they are powered on.

The output of an incremental encoder typically consists of A/B/Z three-phase signals. The outputs of A and B have a phase difference of 1/4 of a cycle (or 90 degrees), with the A-phase leading in forward rotation (1/4 phase difference) and the B-phase leading in reverse rotation (3/4 phase difference), allowing the direction of encoder rotation to be determined. The Z-phase provides only one position pulse per revolution, which can be used to set the zero position value.

Zkseasy's incremental 2500-line magnetic encoder supports servo motors in the power range of 11W to 750W, offering a broader selection. The 2048-line encoder, on the other hand, only supports motors within the power range of 11W, 22W, 33W, and 50W. However, the 2048-line optical encoder also supports matching hollow shaft motors.

Compared to the 2500-line magnetic encoder, the 2048-line optical encoder boasts higher precision, resolution, lower speed fluctuation, better low-speed stability, and higher positioning accuracy, making it more suitable for high-precision and high-resolution measurement applications such as precision machinery, optical instruments, and semiconductor equipment.

Zkseasy's 25mm servo motors can be equipped with either the incremental 2500-line or 2048-line encoder. The 25mm, 40mm, 60mm, and 80mm servo motors can all be configured with the 2500-line magnetic encoder. However, the 2048-line encoder only supports the 25mm flange servo motor.

It's worth noting that incremental encoder micro servo motors have some limitations. Firstly, their output is periodic, requiring the number and direction of counting pulses to determine the motor's position and speed. Secondly, they require zero-position calibration each time they are powered on and may lose current position information when the motor is powered off or subjected to external interference. Absolute encoders can quickly increase angles and pulses, memorize absolute positions, have memory functions, and do not require homing upon startup. When selecting and using incremental encoder micro servo motors, users need to fully consider these limitations and comprehensively consider specific application scenarios and requirements. Therefore, when making a selection, Zkseasy advises users to carefully choose the suitable motor type based on actual needs to ensure system stability and reliability.
