Brief Introduction

This Z2-4 DC Motor is generally industrial small size low noise DC motor, which requires constant power speed range no larger than 2:1, and overload capacity no larger than electric traction of rated torque. The basic structure of motor adopts drop-proof uniaxial extension, self-fan cooled structure, applying in general normal working conditions. This series of motor has fine speed adjusting characteristic, reliable property and no need of direct AC power supply. It is with internal fan and self-ventilation. The motor can operate when the ambient temperature is -15℃~+40℃; Altitude ≤1KM; and monthly average air humidity ≤90% (If temperature is 25℃). This series of motor applies in industries of metal cutting machine, paper-cutting, dyeing and weaving, printing, cement, etc.

 

Engineered for bidirectional electromechanical conversion, this unit implements precision commutation and robust magnetic circuits to deliver reliable performance in both motoring and generating modes.

Core Electromagnetic Systems of low noise DC motor:

Commutator-Brush Interface: Mica-insulated copper segments ensure seamless AC/DC transition while withstanding continuous arcing overloads.

Laminated Armature Core: DR510 silicon steel stacks minimize eddy losses during high-speed rotation, maintaining flux density stability.

Main Pole Assembly: Field coils wound on tapered pole shoes optimize magnetic field distribution across the air gap.

Interpole Integration: Commutation-enhancing poles suppress sparking during load transients via series-connected windings.

 

Construction highlights:
• Die-cast end shields with precision-machined bearing seats
• Resilient brush holders allowing radial adjustment
• Ventilated yoke design dissipating heat from field windings
• Dynamic balancing for vibration-free operation up to 3,600 RPM

 

The Z2-4 low noise DC motor executes critical functions:

Motoring: Converts DC input to torque via electromagnetic force (f=Blia)

Generating: Induces DC output through rotating conductor flux-cutting

Commutation: Sliding brush-contactor system sustains unidirectional current

Cooling: Axial fans maintain thermal stability at full load

Validated for industrial drives and auxiliary power units, its modular design enables rapid maintenance of armature windings, carbon brushes, and pole assemblies. All components comply with IEC 60034-1 standards for electrical machine construction.
