In general, the output current will be greater than the input current.
why?
On the motor side, the power factor is generally low. Generally, the power factor of the rated motor condition (rated output torque) is about 0.8~0.9, and the small motor will be lower, about 0.75. When the motor load is light, the power factor is lower, and the current is mostly the reactive current of the reactive current flowing between the capacitor and the motor. The power factor on the input side will be higher, so the input current will be smaller than the output current.
Therefore, the magnitude of the current is mainly determined by the power factor of the input side and the output side. The current with a high power factor is small, and the current with a low power factor is large.

Incremental Encoder

Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
