Feature: 1. Using all metal gears, come with small size, large torsion, ultra‑quiet, stable operation, very practical 2. The stator and rotor adopt pure copper coils to increase the torsion of the motor, and the deceleration resistance and conductivity are strengthened 3. This brushless motor will automatically cut off the power when the current reaches 3A, avoid burning out during the use of the motor and increase the service life of the motor 4. The lubricating oil applied to the motor gear is high‑temperature grease, come with low friction, noise reduction, and slow temperature rise 5. A total of two magnets in the motor body, which have the characteristics of high remanence, high coercivity, high magnetic energy product, high performance, and high torsion 6. Used in micro‑machines in various industries like circulating fans, humidifiers, dehumidifiers, air fresheners, cold and warm fans, soap dispensers, hand dryers, smart door locks, textile machinery, laser processing machinery, engraving machines, printing machinery, automatic packaging machine Specification: Item Type: DC Gear Motor Model: XD-42GA755 Material: Copper Output Shaft Size: Approx. 8 x 20mm / 0.3 x 0.8in Insulation Resistance: After the rated operation of the motor under normal temperature and humidity, when measuring the insulation resistance between the coil and the motor shell with a DC500V resistance meter, it does not exceed 20MΩ Insulation Withstand Voltage: After the rated operation of the motor under normal temperature and humidity, 50Hz or 60Hz is applied between the coil shells for one minute, and the abnormality is 1500V. Temperature Rise: It is normal to install a gear box or equivalent heat sink and conduct rated operation under normal temperature and humidity by using the resistance method to measure the temperature rise of the coil below 70℃ Insulation Class: Class B(130℃) Operating Environment Temperature: Motor: -10~+40℃ (no icing) Use Environment Humidity: 85% or less (no condensation) CW/CCW: Yes Speed Adjusted: Yes Model Voltage（DC/V） No-Load Speed (rpm/min) No-Load Current(A) Load Speed (rpm/min) Loading Moment（kgf·cm） Reduction Ratio（1:00） Power（W） XD-42GA755 24V 100 0.27 93 4.58 50 25 150 0.27 128 3.06 33 25 200 0.27 175 2.29 25 25 300 0.27 245 1.53 16.6 25 500 0.27 435 0.92 10 25 600 0.27 535 0.76 8.3 25 Notes: 1 Overload and Locked Rotor: When the motor is running, it generates heat due to the energy conversion that occurs inside the coil and the iron core, and the temperature gradually rises. The load is within the rated range, and the heat generation and heat dissipation are balanced, and the coil of the motor will not be burnt. However, it will cause heat under overload and locked-rotor conditions. When the running time is too long, the insulating film on the enameled wire of the coil is dissolved, causing a short circuit between the enameled wires and burning the motor. 2 When Running at Low Speed: For DC motors, carbon brushes are generally used. The rotating commutator rubs against the carbon brushes, creating sparks at the notches of the commutator. When the motor is running at a low speed, the carbon brush powder that is easily generated by the friction between the commutator and the carbon brush will accumulate in the commutator slot, causing a short circuit and burning the motor and driver. Please be very careful. 3 Precautions on the PWM Controller: When using the PWM controller, the carbon brushes have a shorter service life than in the rated voltage (or fixed voltage) state. In addition, depending on the frequency of use, carbon brushes may wear out quickly. The frequency of PWM control of DC motors is generally 10-20KHz, and repeated ON-OFF during PWM control can save energy. However, the parts used in the motor are similar to the frequency of use, which will cause resonance and heat. Please pay full attention to use. In the PWM control state, when using the built-in motor of the electrolytic capacitor, the motor may not rotate at a certain fixed frequency. Please try to use varistor to hide the motor. (Need to do related tests) 4 Regarding Inertia and Braking: After the motor is powered off, the rotor will still rotate due to inertia, which is the inertia of the DC motor. If you want to stop the rotation immediately, you can short-circuit the positive and negative terminals after turning off the power. The use of this kind of brake is to use the motor to generate electricity (reverse current). The current may increase temporarily and shorten the life. 5 Treatment of Floor Motor: Because the magnetic tile is a brittle material, the DC motor may break the magnetic tile once it falls, causing the motor to block and cause burns. Please do not use the motor after it has landed at a high altitude. . Package List: 1 x DC Gear Motor1 x Bracket
