ZEXEL RM-F6JUPM-CH 158908-4200 Reversible Speed Adjustment Motor

Overview

The ZEXEL RM-F6JUPM-CH 158908-4200 is a reversible speed adjustment motor manufactured by Zexel, widely used for marine diesel engine governor and fuel rack actuator control. The ZEXEL RM-F6JUPM-CH 158908-4200 executes forward and reverse rotation to adjust the fuel injection rack position, thereby regulating engine speed and output power. It features compact structure and stable torque output, designed for long-term vibration-resistant operation in marine engine rooms. The ZEXEL RM-F6JUPM-CH 158908-4200 is a classic spare part for emergency repair and replacement of Zexel marine governor systems.

Features

The ZEXEL RM-F6JUPM-CH 158908-4200 supports bidirectional reversible rotation for fuel rack increase and decrease control. It matches the original governor mechanical linkage and wiring definition for direct replacement. The ZEXEL RM-F6JUPM-CH 158908-4200 runs on low current with low heat generation and reliable holding torque. It is built to withstand humidity, vibration and temperature fluctuation inside marine engine compartments. The ZEXEL RM-F6JUPM-CH 158908-4200 works with governor controller to form closed-loop engine speed regulation.

Specs

Device Type: Reversible speed adjustment motor Model: ZEXEL RM-F6JUPM-CH 158908-4200Rated Voltage: 100V / 110V / 115V AC, 50/60Hz Rated Power: 4 W Rated Current: 0.18 A Speed: 1200–1450 RPM Capacitor: 2μF Duty Cycle: 30 min intermittent duty Application: Marine diesel engine governor fuel rack drive Environment: Marine engine room

Principle

The ZEXEL RM-F6JUPM-CH 158908-4200 receives forward or reverse drive signal from the governor control unit. The motor rotates and drives the linkage mechanism to push or pull the fuel rack of the injection pump. The governor compares engine speed feedback signal with setpoint continuously. When speed deviation appears, the ZEXEL RM-F6JUPM-CH 158908-4200 rotates in corresponding direction to adjust fuel supply and stabilize engine speed.

Applications

The ZEXEL RM-F6JUPM-CH 158908-4200 is used for main engine and auxiliary engine governor maintenance on seagoing vessels. It serves fuel rack actuation for diesel generator speed control systems. The ZEXEL RM-F6JUPM-CH 158908-4200 applies to spare stock and troubleshooting of existing Zexel governor units. It also works for diesel engine test bench speed regulation actuator replacement.
