GLOBAL EXTERNAL ROTOR MOTOR MARKET

INTRODUCTION

 An electric motor with an external rotor has the rotor outside of the stator, making it appear as though the motor has been turned inside out. In radio-controlled model aircraft, they are frequently utilised. Similar to the motors utilised in standard CD-ROM computer drives, this sort of motor spins its outer shell around its windings.

In reality, brushless outrunner motors for little park flyer aircraft are routinely made from CD-ROM motors. Commercially accessible components make it easier to adapt CD-ROM motors for use in aircraft. Outrunners typically have more poles than their in runner counterparts, which causes them to spin more slowly and provide greater torque.

As a result, outrunners are a great option for directly operating electric aircraft propellers since they do so without the additional weight, complexity, inefficiency, and noise that they would otherwise produce.

The extra weight, complexity, inefficiency, and noise of a gearbox are all eliminated, making an outrunner a great option for directly operating electric aircraft propellers. Outrunner motors have gained popularity quickly and are now offered in a variety of sizes.

Due to their small size and excellent efficiency, they have also gained popularity in personal, electric transportation applications such electric bikes and scooters. This makes an outrunner a fantastic option for directly powering an electric vehicle.

Conventional DC brushless motor controllers activate the stationary windings of an outrunner motor. Typically, three or more non-adjacent windings are combined with a direct current (switched on and off at high frequency for voltage modulation), and the group so powered is cycled electronically based on feedback from the rotor position.

Nevertheless, the number of stator poles and permanent magnets in the rotor are not equal. To lessen cogging torque and produce a sinusoidal back emf, do this. The ratio of magnetic field frequency to motor rotation frequency is calculated by dividing the number of magnet poles by 2.

GLOBAL EXTERNAL ROTOR MOTOR MARKET SIZE AND FORECAST

The Global External Rotor Motor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.

NEW PRODUCT LAUNCH

Nanotec now provides a flat external rotor motor with a 20 mm diameter, the DF20. Digital Hall sensors are included for easy operation, and it is available with two alternative windings for 12 and 24 V. The DF20 has a 5 W rated power and a 5,200 rpm rated speed.

Even at high speeds, the open design without a rotor housing ensures ideal heat dissipation. This brushless DC motor is perfect for applications with limited space because of its compact design with flat ribbon cable, such as robot grippers, medical pumps, or prosthetics. As an add-on, an adapter board is offered for testing.

The DF20 completes the external rotor motor family from Nanotec, which also comprises motors with 32 and 45 mm diameters.
