AI Technical Summary
Existing multi-turn encoders have small battery capacities, leading to frequent power outages and increased maintenance costs.
An energy storage module is set in the motor controller, including a system power module, a first power selection module and an energy storage module. The energy storage module of the motor controller itself is used to power the encoder, reducing the dependence on the encoder battery.
By increasing the capacity of the energy storage module, the frequency of battery replacement is reduced, maintenance costs are lowered, and the efficiency of power supply management is improved.
