Product Overview
The JD1A-40 electromagnetic speed-regulating motor control device is a core component designed for YCT series adjustable-speed motors, utilizing electromagnetic slip clutch technology to achieve AC stepless speed regulation. When paired with three-phase induction motors, this system provides wide speed range (1250-125rpm at 50Hz) with ≤2.5% speed variation rate, ideal for constant torque applications. Its manual operation via panel-mounted potentiometer enables smooth speed adjustment, while built-in speed negative feedback automatically maintains rotational stability. 313
Technical Features
Employing phase-shift triggering and thyristor rectification, the controller compares speed command signals with tachometer feedback to regulate excitation current for precise control. With 90VDC maximum output, it accommodates 15-40kW motors and operates at AC220V±10% voltage. The IP5X-rated enclosure supports both panel-mounted and wall-hung installation, featuring a 7-pin aviation socket for simplified wiring. Calibration potentiometers allow speed display accuracy adjustment and feedback tuning to match motor nameplate specifications. 419
Applications
Widely used in light industrial machinery, paper production lines, and food processing conveyors requiring continuous speed adjustment. Particularly effective for energy saving when driving fan or pump loads. Compatible with three-phase medium-frequency tachogenerators (2V/100rpm), the device maintains stable operation within -5℃ to +40℃ ambient temperature and 90% relative humidity, with vibration resistance meeting 10-150Hz/0.5g industrial standards. 824
Safety & Maintenance
Integrated overload protection requires pre-use insulation resistance verification (≥1MΩ at 500V). Maintenance involves keeping the environment clean and avoiding liquid ingress. For prolonged storage, 45℃ low-temperature drying is recommended. Component replacement should use ≤45W soldering irons with <5-second welding duration, followed by alcohol cleaning and protective coating on PCB. Typical troubleshooting includes checking potentiometer contacts, voltage regulator capacitors, and pulse transformer waveforms. 2227

一、概述
該控制器是在原機(jī)械工業(yè)部聯(lián)合設(shè)計(jì)的電磁調(diào)速電動(dòng)機(jī)控制器基礎(chǔ)上經(jīng)過(guò)改制而成,性能更加穩(wěn)定、穩(wěn)速精度更高。主要用交流電磁調(diào)速電動(dòng)機(jī)(滑差電機(jī))的調(diào)速控制、實(shí)現(xiàn)恒轉(zhuǎn)矩?zé)o級(jí)調(diào)速,當(dāng)負(fù)載為風(fēng)機(jī)和泵類時(shí),有明顯的節(jié)能效果。
二、調(diào)試步驟
檢查零件是否有松脫現(xiàn)象,保險(xiǎn)絲規(guī)格是否正確,轉(zhuǎn)速表指針是否在零位。
接通電動(dòng)機(jī)電源,檢查旋轉(zhuǎn)方向是否被拖動(dòng)機(jī)械一致。
試車時(shí),先起動(dòng)異步電機(jī),再接通控制器電源,指示燈亮,旋動(dòng)調(diào)速旋鈕,此時(shí)轉(zhuǎn)速表逐漸上升,根據(jù)實(shí)現(xiàn)需要,設(shè)定轉(zhuǎn)速值。
轉(zhuǎn)速表校正因?yàn)闇y(cè)速發(fā)電機(jī)個(gè)體的差異,在配用新的調(diào)速器前要進(jìn)行轉(zhuǎn)速表校正調(diào)節(jié),先設(shè)定轉(zhuǎn)速在1200r/min時(shí),用其它標(biāo)準(zhǔn)的轉(zhuǎn)速表比對(duì)面板上的轉(zhuǎn)速表,調(diào)節(jié)面板上轉(zhuǎn)速表校準(zhǔn)電位器,使實(shí)際轉(zhuǎn)速與顯示轉(zhuǎn)速相符。
