HT4310 motor without encoder

Order the HT4310 encoderless motor for your drone and get reliable thrust and simplicity!

HT4310 motor without encoder for drone is a classic brushless motor for various aircraft. It creates powerful thrust for lifting the quadcopter and maneuvering. This engine has a simple and reliable design. It is suitable for many amateur and professional projects. You will get stable operation and long service life.

This motor operates on the principle of brushless technology. It has no brushes, which reduces wear and increases efficiency. The motor is directly connected to the propeller. The stroke controller controls the rotation speed through three phases. This system provides smooth and powerful acceleration.

• High reliability thanks to the brushless design.

• Powerful traction for lifting heavy vehicles and dynamic flights.

• Easy to install and configure without complex feedback systems.

• Efficient Cooling due to high-quality case materials.

• Versatility for use on different types of drones.

How does a brushless motor work?

The motor receives three-phase alternating current from the speed controller. Current is supplied to the stator windings in a certain sequence. This creates a rotating magnetic field. It interacts with the permanent magnets of the rotor. The rotor begins to rotate, transmitting torque to the propeller.

The absence of an encoder simplifies the design and reduces cost. An encoder is usually needed for precise positioning in closed-loop systems. For example, in industrial manipulators or machine tools. This is not required for quadcopter flight. The flight controller controls the engine without shaft position feedback. This is a classic and proven design for most drones.

Specifications and Features

The HT4310 model has standard parameters for its class. The first two digits (43) indicate the stator diameter in millimeters. The second two numbers (10) indicate the stator height. This is an important parameter for assessing power and torque. The motor has a certain KV value. It shows the number of revolutions per minute per volt of voltage.

The operating voltage is usually 3-6S for LiPo batteries. The maximum power can reach several hundred watts. The body is made of aluminum alloy for good heat dissipation. The shaft is made of hardened steel for resistance to stress. The bearings ensure smooth rotation with minimal resistance.

This motor is suitable for various applications. It can be used on cargo and filming multicopters. It is also installed on racing drones where traction is important. For freestyle it provides a good balance of power and control. The main thing is to choose the right propeller and battery. This will reveal the potential of the motor.

Engine installation is standard for such models. You need to secure it to the frame beam with screws. Then solder three power wires to the speed controller. The polarity of the phases does not matter for the direction of rotation. It can be changed by swapping any two wires. After this, the motor is ready for calibration and tuning in the flight controller.
