Core Technology
Brand-new space vector technology
The advanced vector algorithm ensures high torque at low frequencies, maximizes grid voltage utilization, and delivers optimized sinusoidal output—all while achieving the lowest possible switching losses. As a result, it reduces motor operating noise and minimizes heat generation.
Unique software dead-zone compensation
Dead-time is the primary culprit behind low-frequency pulsating torque generated by variable frequency drives. Ruiyi’s unique software-based dead-time compensation ensures maximum smoothness of torque even under low-frequency, high-speed operating conditions.
Excellent speed-tracking self-starting without a speed sensor
The Ruiyi product can start motors that are already running, ensuring smooth and continuous operation of user equipment. It automatically recognizes the rotational speed and achieves stable speed tracking.
Automatic energy-saving operation
Unique software-based power factor regulation dynamically adjusts the power factor according to load changes, saving even more energy.
Voltage fluctuation suppression
The dynamic automatic voltage control (AVC) function ensures that when the input voltage fluctuates by ±20%, the output voltage fluctuation remains below ±5%.
Friendly human-machine interface, flexible input/output interfaces
The CD supports both Chinese and English display, and provides 8 digital inputs, 2 analog inputs, 3 digital outputs, and 2 analog outputs. The eight segments can be programmed by the user and feature an electric potentiometer setting mode.
Powered by DC power supply, saving on investment in backup power systems.
Built-in flexible PWM energy-regenerative braking—users can easily implement energy-regenerative braking by selecting the appropriate braking resistor.
Intelligent Lubrication for Industrial and Mining Equipment
It features protection functions including overvoltage, overcurrent, undervoltage, IGBT short-circuit, and inverse-time overload protection. Additionally, it can provide safe protection even in the event of a load short circuit or ground fault.
