MCI375PT4C66STR1D0F00X400 Permanent Magnet Synchronous Servo Motor Product Description

Overview

MCI375PT4C66STR1D0F00X400 is a high‑torque permanent magnet synchronous servo motor from the MCI series, a custom long‑code model with integrated encoder, brake and special shaft/flange configuration. This servo motor is designed for high‑dynamic closed‑loop positioning, speed and torque control, commonly matched with multi‑axis servo drives for heavy‑duty automation machinery. MCI375PT4C66STR1D0F00X400 is a project‑specific order number, and the suffix string defines winding, encoder type, holding brake, shaft form, sealing, cable outlet and special mechanical modification. It is widely used for new machine build, production line upgrade and spare‑part replacement of the original matched motion system.

Features

MCI375PT4C66STR1D0F00X400 servo motor adopts high‑energy density permanent magnet rotor design for high torque density and low cogging torque. This servo motor integrates high‑resolution absolute encoder for reliable position retention after power loss, eliminating the need for homing on restart. MCI375PT4C66STR1D0F00X400 is fitted with built‑in holding brake for vertical axis load retention when power is cut off. The servo motor supports IP65 / IP67 enclosure protection, suitable for workshop environments with dust, coolant splash and humidity. This servo motor supports cyclic high acceleration/deceleration operation and can run in position, speed and torque modes according to drive commands. The full part number string locks custom parameters, so substitutions cannot rely only on the basic frame size.

Principle

MCI375PT4C66STR1D0F00X400 servo motor receives three‑phase PWM power and motion commands from the matched servo amplifier. The permanent magnet rotor generates rotary motion under the rotating magnetic field from the stator winding. The built‑in absolute encoder continuously feeds rotor angle and position back to the drive to form a closed control loop, supporting precise positioning, speed regulation and torque limiting. When the enable signal drops out, the holding brake engages mechanically to lock the shaft and prevent load falling on vertical axes. The drive monitors motor current, encoder signal and winding temperature for overcurrent, overspeed and overheat protection.

Applications

MCI375PT4C66STR1D0F00X400 servo motor is widely deployed in metal processing equipment, injection moulding machines, automated press stations, packaging lines and gantry handling systems. This servo motor is selected for heavy‑load indexing, feeding, pressing and synchronized motion tasks. MCI375PT4C66STR1D0F00X400 is mainly used for spare replacement of the same unique model in existing automated lines, as the long part number contains custom mechanical and electrical requirements that standard general models cannot replace directly.

Installation & Maintenance Notes

Follow the manufacturer’s servo hardware manual during installation of MCI375PT4C66STR1D0F00X400 servo motor. Align the coupling carefully and avoid radial and axial overload that can damage the encoder and bearing. Use shielded dedicated power and encoder cables and ensure good grounding for EMC performance. Test brake release and holding function separately for vertical axis applications. Periodically inspect bearing noise, sealing condition, connector tightness and cable abrasion under high‑cycle operation. Back up drive parameters before replacement. Confirm the full complete part number MCI375PT4C66STR1D0F00X400 before spare‑part swap‑out to verify encoder protocol, brake, shaft size, flange and winding voltage compatibility.
