High Torque Variable Speed DC Motor

Title:

Z630-1A High Torque Variable Speed DC Motor

Brief Introduction

Engineered for versatile speed regulation, this industrial DC motor implements three fundamental speed-adjustment methodologies without compromising torque integrity.

Core Speed Control Technologies:

Armature Voltage Modulation: Achieves linear speed reduction under lowered supply voltage while maintaining stable torque output, ideal for battery-powered applications requiring incremental speed control.

Resistive Circuit Optimization: External rheostat integration enables adjustable armature resistance for extended speed range under heavy loads, despite progressive power dissipation at lower speeds.

Field Flux Weakening: Permits speed elevation beyond base rating by reducing excitation current, operating in constant-power mode with embedded thermal protection against overloads.

Critical design implementations include:
• Commutator-brush assembly rated for continuous current interruption during dynamic braking
• Laminated pole shoes preventing magnetic saturation during field weakening
• Ventilated frame design dissipating resistive losses during armature circuit control
• Interlocked excitation safeguards preventing dangerous over-fluxing

The Z630-1A executes specialized operations:

Seamless transition between constant-torque and constant-power modes

Regenerative capability during voltage step-down sequences

Carbon-brush maintenance access points for resistance grid servicing

Thermally stable windings enduring field-weakening induced eddy currents

Validated for traction systems, extruders, and winding machinery, it eliminates gearbox dependencies through direct 10:1 speed variation capability. Includes terminal markings for independent armature/excitation wiring per IEC DC drive standards.

Main Technical Parameters

Why choose Simo Brand Z DC Motor?

Z series DC motor is developed and improved based on Z4 series DC motor. The motor has outstanding advantages of wide speed control, good overloading capability, and good adaptation according to different working environment. 

This series of motors can be supplied not only by DC generator group, but also more suitable for static rectifying power supply. And moment of inertia is small, the dynamic performance is good, and can withstand a higher rating of load changes, especially suitable for control systems that require smooth speed control, high efficiency, automatic speed stability, sensitive response.
