Product Description

The MG945 High-Speed Metal Gear Digital Servo Motor is a durable and high-torque servo designed for RC cars, boats, helicopters, airplanes, trucks, racing cars, and other RC models. It features an all-metal gear system and double ball bearings, providing stable operation and improved durability for demanding applications.

With an operating voltage range of 4.8–7.2V, the MG945 offers an operating speed of 0.18 seconds per 60° at 6V under no load and a specified stall torque of 15 kg·cm at 6V. Its standard receiver connector makes it compatible with commonly used RC systems from Futaba, Hitec, Sanwa, GWS, and similar systems.

The servo provides a practical solution for RC hobbyists, robotics enthusiasts, and DIY developers looking for a reliable metal-gear servo for steering, control surfaces, mechanical linkages, and other motion-control applications.

Specifications

Working Principle

The MG945 digital servo receives a control signal from an RC receiver, microcontroller, or compatible servo controller. The internal control circuit compares the commanded position with the servo’s actual position and drives the motor accordingly.

The motor transfers its rotation through the metal gear train, producing controlled angular movement at the output shaft. The double ball-bearing arrangement helps support smooth and stable mechanical operation.

The servo can be controlled to move to different angular positions within its usable rotation range, making it suitable for steering mechanisms, control surfaces, robotic joints, and other motion-control applications.

Design and Construction

The MG945 uses a robust housing with an all-metal gear train designed for applications requiring greater mechanical durability than basic plastic-geared servos.

Its double ball-bearing configuration supports the output mechanism and helps provide stable movement. The servo also includes a connector cable for direct connection to compatible RC receivers and servo controllers.

With dimensions of approximately 40.6 × 19.8 × 42.9mm, the servo can be installed in many standard RC and mechanical applications.

Compatibility

The MG945 uses a standard-style RC servo connector and is designed to work with compatible receiver systems from brands such as:

• Futaba
• Hitec
• Sanwa
• GWS
• Other compatible RC systems

Always verify connector polarity and voltage compatibility before connecting the servo.

Product Disclaimer

• The stated 15 kg·cm stall torque is specified at 6V and should not be treated as continuous operating torque.
• Operating speed is specified at 6V under no-load conditions.
• Ensure the servo is supplied with a suitable voltage within the specified 4.8–7.2V range.
• Actual performance may vary depending on load, power supply, mechanical installation, temperature, and operating conditions.
• Avoid forcing the servo beyond its mechanical limits.
• Connector compatibility should be checked before connecting to an RC receiver or controller.
