Product Overview

The DK-2 series speed-regulating motor control combination device is a precision control equipment specifically designed for electromagnetic speed-regulating motors, suitable for stepless speed regulation in various industrial scenarios. Compatible with JZT and YGT series motors, this modular system offers both manual operation and automatic signal input capabilities, supporting synchronous/proportional control of single or multiple motors. Its applications span across papermaking, chemical fiber, and printing production lines where precise speed adjustment is critical.116

Technical Specifications

Featuring a wide speed range of 120-1370rpm with ≤2.5% speed variation rate, the device delivers 90V/5A DC output powered by AC220V supply. It accommodates motors from 0.55KW to 90KW and accepts multiple control signals including 0-10V DC and 4-20mA. The integrated speed negative feedback system enhances mechanical rigidity, minimizing speed fluctuations under load variations. User-friendly digital display and rotary potentiometer simplify on-site calibration, while LED indicators provide real-time operational status monitoring.21720

Functional Features

Operation modes can be flexibly switched between internal potentiometer control and external signal input (e.g., DDZ-II regulator). The built-in voltage differential negative feedback circuit effectively suppresses interference for smooth acceleration/deceleration. For variable torque loads like fans and pumps, the device automatically optimizes excitation current to maintain high efficiency at low speeds. Standard protection mechanisms include overcurrent cutoff to safeguard motor and clutch components. Multi-unit synchronization is achievable through TC-1A master controller interconnection.31326

Performance Advantages

The compact enclosure (160×80×420mm) combines space efficiency with superior heat dissipation, meeting IP5X dust protection standards. With ±1% speed regulation accuracy, it supports calibration for various tachogenerators (≥2V/100rpm). Specially designed trigger circuits ensure linear thyristor conduction angle variation, delivering exceptional low-speed torque characteristics. Industrial-grade components guarantee stable operation within -5℃ to +40℃ ambient temperature, achieving over 20,000 hours MTBF. The maintenance-free design requires only periodic dust cleaning for prolonged service life.121529

Typical Applications

Widely implemented in ceramic roller conveyors, cement conveyor belts, and chemical fiber spinning machines requiring precise speed coordination. In printing presses, it enables multicolor unit synchronization for accurate registration. Textile applications benefit from constant yarn tension control. Particularly effective for energy-saving retrofits in fan/pump systems, replacing throttle valves with speed regulation can reduce energy consumption by 10%-30%. The dust-proof construction also suits wood processing and grain handling environments with high particulate concentrations.52125
