Technical Specifications Controlled Object: Series‑wound DC traction motor Input Power: Battery DC power input Control Mode: Pulse width modulation power regulation Signal Interface: Analog and digital control signal input terminals Protection Function: Over‑current, over‑temperature hardware protection Operating Temperature: ‑20 ℃ to +65 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Metal‑cased power module for equipment chassis mounting Certifications: CE industrial power component compliance
Functional Features Realizes high‑power DC traction motor speed adjustment and driving control. Pulse width modulation mode outputs adjustable power to control motor rotating speed. Built‑in multiple protection mechanisms including over‑current and over‑temperature protection. Receives operation command signal from upper control unit. Fault status feedback signal output for host system fault diagnosis. Metal housing provides heat dissipation capacity for power circuit.
Application Scenarios DC traction motor driving for industrial battery‑powered electric vehicles and forklift equipment. Power control unit for material‑handling moving machinery. Spare‑part replacement for legacy industrial DC drive equipment adopting IC3645 series hardware.
Structural Characteristics Heavy‑duty metal enclosure with internal heat‑dissipation structure. High‑current power terminals for battery and DC motor connection. Low‑current signal terminals for control command and fault‑signal wiring. Mounting holes for fastening onto equipment chassis.
Working Principle Battery DC power connects to module power input terminals. After receiving speed and direction control signal from upper controller, internal power circuit adjusts output power by pulse‑width‑modulation method, so as to control DC traction motor rotating speed and running state.
Installation Requirements Securely fasten module onto equipment chassis by mounting holes, guarantee good heat‑dissipation condition. Complete high‑current power wiring for battery and DC motor, match proper cable gauge for heavy‑current loop.
