GDM120N-528/0750

Dimension & Weight Parameter
Overall outer diameter of the motor body reaches 120mm matching its GDM120N series specification, axial mounting thickness is approximately 42mm; standard shaft dimension complies with factory IM B14 mounting flange standard. The net weight of single finished motor stands at around 4.5kg, consistent with GDM120N series universal weight benchmark of the same frame size.
Electrical Performance Parameters
Rated operating voltage is 24VDC direct current; rated nominal working current is 8.6A under continuous duty cycle. Rated output mechanical torque hits 70N·cm, rated rotational speed is 2050 revolutions per minute with rated output power up to 150W; protection grade of the whole motor housing is IP44 for dustproof and splash-proof protection per IEC standard.
Ambient & Operating Temperature Specifications
Continuous working ambient temperature range covers -20°C to +40°C complying with DIN EN 60721-3-3 industrial environmental classification 3K3 standard; permissible storage temperature spans -40°C to +70°C under 1K4 grade requirement, and transportation applicable temperature ranges from -30°C to +60°C as specified for Class 2K3. Maximum allowable winding temperature rise is limited at 105K under rated continuous load operation with natural air cooling (IC410 cooling mode).
Core Product Characteristics
The coreless rotor design completely eliminates cogging torque to deliver smooth output torque with negligible torque fluctuation across full speed regulation range. Robust drum-shaped commutator and optimized armature inductance structure effectively lower carbon brush abrasion rate and extend regular maintenance interval, while NdFeB high-energy permanent magnet enables high continuous torque output under compact volume and superior short-time overload capacity. Ultra-low inertia property brings excellent acceleration and deceleration dynamic performance to realize fast servo positioning response, plus wide constant-torque working scope for stable speed adjustment from near-zero speed up to rated rotation speed. Standard terminal wiring structure supports convenient field wiring, and multi-optional auxiliary accessories expand application flexibility for closed-loop servo control scenarios.
