Application in Peristaltic Pump Equipment
The STM57E series integrated motor upgrades peristaltic pumps from "coarse conveyance" to "precision intelligent pumping." It is particularly suitable for applications with extremely high demands on flow accuracy, tubing life, and system immunity, such as IVD reagent dispensing, biopharmaceutical filling, and continuous feeding in culture processes. If you need a detailed comparison of energy efficiency differences between closed-loop stepper and AC servo motors in this application, I can provide further analysis.
