Synchronous Turntable Motor High-Torque Microwave & Display Rotation
This Synchronous Motor (Model MDS-4A) is a precision-engineered component designed for low-speed, high-torque applications. It is most commonly used as a replacement motor for microwave oven turntables, ensuring smooth and consistent rotation for even heating.
Key Performance Features
-
Steady Rotation Speed: Operates at a consistent 4 / 4.8 RPM (revolutions per minute), providing the ideal pace for microwave turntables and mechanical displays.
-
Bi-Directional Capability: Designed as a synchronous motor that can rotate in both directions depending on the initial electrical phase.
-
High-Efficiency Design: Consumes minimal power while delivering the necessary torque to rotate heavy glass plates or display stands.
-
Durable Construction: Features a rugged metal housing and a high-strength plastic drive shaft to withstand the humid and warm environments inside kitchen appliances.
-
Standardized Terminals: Equipped with two flat spade-style male connectors for easy "push-on" wiring during installation.

Top 3 Customer Questions & Concerns
How do I know if my microwave motor is broken? If your microwave heats up but the glass tray no longer spins, or if the tray makes a grinding noise and jerks while moving, the motor likely needs replacement.
Is it hard to install? Most microwave motors are accessible by removing the bottom panel of the appliance. It typically involves removing two screws and swapping the two wire leads. Always unplug the microwave before attempting any repair.
Does the direction of the wires matter? No. Since this is an AC (Alternating Current) synchronous motor, the two wires can be connected to either terminal without affecting the performance or safety of the unit.
