Maplef Electrical Multi-Turn Actuator

1. High-Quality Housing: High-quality aluminum alloy shell, compact and lightweight, with protective material suitable for
extremely harsh environments; other types of coatings are available upon request.
2. Advanced Motor Design: The low-inertia, high-torque motor enables it to reach peak torque quickly after startup, with
almost no overrun when de-energized. A precise temperature switch is embedded in the motor coil and is unaffected by
ambient temperature, ensuring optimal thermal performance. Additionally, the motor shaft and worm gear are independent, allowing for quick and easy replacement.
3. User-Friendly Control Panel: The control panel LCD provides instantaneous, up-to-date status and valve position, is available in English, and uses a straight menu structure to provide calibration and diagnostic information. It includes torque lines,
operation and fault records, motor status, machine information, and hardware data.
4. Double-Sealed Terminal Box: The double seal design provides a sunflower terminal box that is separated from the control
room and sealed. Even if the terminal box cover is opened in the field, it ensures isolation between the inside of the actuator
and the outside world, so that moisture, dust, harmful gases, etc., will not enter the inside of the execution structure, and the
internal components are fully protected.
5. Accurate Torque Measurement: The output torque measurement system uses a professionally designed useful work measurement system developed from familiar electrical energy measurement techniques to obtain accurate and repeatable
torque measurements, independent of changes in frequency, voltage, and temperature.
6. Modular Control Unit: The control unit consists of control, monitoring, and protection modules; adopts a clasp-cage type
installation structure with shock absorption and buffering; and uses plug-in connections to ensure quick and error-free module removal and replacement.
7. Efficient Worm Gear Transmission: The worm gear transmission chain has a simple, compact structure and constant transmission efficiency, with a mechanical self-locking function, requiring no brake. The transmission part is filled with long-lasting
lubricating oil, allowing for long-term operation without maintenance.
8. Robust Position Sensor: The position sensor of the MSV series electric actuator adopts self-developed multicircle magnetic
absolute encoder technology, which features wear resistance, shock resistance, long service life, high resolution, and resistance to low and high temperatures (from -50°C to 120°C).
MSV Series Product Communication Technology
Fieldbus is a development trend in industrial control technology, significantly reducing the cost of communication systems.
Among these, serial communication is considered one of the most innovative methods. Various fieldbus systems have been
developed to control field equipment and actuators. Improvements in plant efficiency, remote parameter setting, and
factory asset management would not be possible without fieldbus technology.
The MSV electric actuator, equipped with a fieldbus interface, represents the world’s most advanced technical level. Many
different fieldbus systems are widely used in actuators, including:
◘ Modbus RTU
◘ HART Modbus
◘ Profibus DP
With fieldbus technology, actuators transition from centralized control to decentralized control. This simplifies system design,
improves operational reliability, and saves users significant installation and maintenance costs.
