Absolute Encoder Integrated Stepper Motors
Absolute encoder integrated stepper motors combine the advantages of closed-loop stepper motor technology with the position retention capability of absolute encoders. Unlike incremental encoders that lose position information when power is removed, absolute encoders retain the exact rotor position, eliminating the need for homing sequences after power-up or system interruptions. This feature is critical for applications where downtime for re-homing is unacceptable or where the system must resume operation immediately after a power cycle.
Adampower's absolute encoder integrated motors are available in NEMA14 through NEMA34 frame sizes, using single-turn or multi-turn absolute encoder technology. These motors integrate the stepper motor, driver, and absolute encoder into a single housing, providing the ultimate in motion control convenience and reliability.
