Summary
By replacing the original 15kW asynchronous motor with a 5.5kW permanent magnet synchronous motor (PMSM), we achieved a remarkable 47% energy saving. This significant reduction in power consumption not only lowers operational costs but also enhances equipment efficiency. This retrofit case clearly demonstrates how Ciitto Servo's PMSM solutions help clients save energy and money while upgrading their production systems.
