Fadal - Glentek DC Axis Motor, Rotary, GM4020 - MTR-0003

Fadal Glentek DC Axis Motor — MTR-0003 / GM4020

The Fadal MTR-0003 is a DC brush servo motor manufactured by Glentek, also known as Glentek part GM4020 (formerly GM4020FS). This is the standard rotary axis motor for Fadal rotary head attachments, providing resolver position feedback and precision DC tachometer velocity feedback for smooth contouring and accurate surface finishes.

Part number cross-reference: Fadal MTR-0003 = Glentek GM4020 = Glentek GM4020FS (legacy designation)

Compatible Fadal rotary models:

• TR65 A axis
• VH65
• VH5C
• VH6, VH8, VH9, VH11 Index DC Rotary models
• TR80

Feedback system:

• Resolver feedback for position control
• Precision DC tachometer for velocity feedback ensures smooth rotation and optimal surface finish quality

Compatible DC brush amplifiers: Glentek AMP-0006 · Glentek AMP-0021

Important installation note: Always reduce the amplifier current limit when installing this motor. Excessive amperage causes permanent winding damage. Do not substitute a generic DC motor — the Glentek MTR-0003 is matched specifically to the Fadal servo system for correct tachometer voltage output and commutator geometry.

All MTR-0003 units shipped from THECNCSOURCE are new. Never cleaned, painted, or misrepresented as remanufactured.

Compatible Fadal VMC models with rotary attachments: VMC 4020 · VMC 3016 · VMC 4525 · VMC 6030 · all VMC models equipped with TR65, VH65, or VH5C rotary head
