Closed-Loop Stepper Motor + Driver Set - 86 Flange 8.5N·m 143mm Body Length Model 86EEP147ALC/ZMD-2HA865
Product features
Closed-Loop Stepper Motor is a high-performance upgraded version of open-loop stepper motors. By integrating an encoder (position feedback device), it achieves closed-loop control featuring "command-execution-feedback-correction". It retains the advantages of simple structure and easy control from open-loop stepper motors while completely solving pain points such as step loss and position deviation. While ensuring positioning accuracy, it also improves dynamic response and load capacity, becoming the preferred power component for scenarios requiring high precision, stability, and reliability in the automation field.
● Adopting an integrated design of "stepper drive + position feedback", the motor works as follows: After the driver sends pulse commands, the motor rotor rotates at the set step angle, and the encoder real-time collects the actual rotor position and feeds it back to the driver. If a deviation between the actual rotor position and the command position is detected, the driver immediately adjusts the pulse signal automatically for compensation, ensuring the motor executes each step accurately. Its core features include:
● Precision & No Step Loss: The encoder provides real-time position feedback to dynamically correct deviations, with a step loss rate close to zero. The positioning accuracy can reach ±0.01mm (depending on encoder resolution), meeting high-precision transmission and positioning requirements;
Product advantages
● High Dynamic Performance: Under closed-loop control, the response speed is increased by more than 30% with better acceleration performance. It operates without jitter at low speeds and no step loss at high speeds, suitable for scenarios requiring high-frequency start-stop and rapid positioning;
● Strong Load Capacity: Compared with open-loop stepper motors of the same specification, the output torque is increased by 20%-50%, enabling it to drive larger loads. It can avoid stalling through feedback adjustment when overloaded, ensuring stable operation;
● Energy Efficiency: Dynamically adjusts output current according to actual load requirements, automatically reducing current under no-load or light-load conditions. Energy consumption is 20%-40% lower than that of open-loop stepper motors, reducing energy costs during long-term operation;
● Enhanced Reliability: Retains the structural advantage of no brushes or vulnerable components, combined with closed-loop protection mechanisms (overcurrent, overload, step loss alarms), resulting in a lower failure rate and adaptability to long-term continuous operation in industrial environments.
