1Using all metal gears with great workmanship, which is wearresistant, quiet, and long service life 2Professional design and reasonable structure, the product has small size and large torsion, ultraquiet and stable to operate 3Adopt pure copper coil, the deceleration resistance and conductivity are strengthened, so that the motor torsion is increased 4With overload current protection function, when the current reaches 3A, the motor will automatically cut off the power to protect it to avoid burning out during the use of the motor and increase the service life of the motor 5Mainly used in various industries such as micro machinery, various CNC machine tools, highaccuracy measuring instruments, electronic manufacturing equipment, financial machinery, military industry and other industries 6The lubricating oil applied to the motor gear is high temperature grease, which has the characteristics of low friction, noise reduction, slow temperature rise, etc., and improves the service life of the gear 7There are two sector magnets in the motor body, which have the characteristics of high remanence, high magnetic energy product, high performance, and high torsion, which can improve the performance of the motor. Item Type: DC Reduction Motor Model: XD-37GB520 Material: Copper Output Shaft Size: Approx. 6 x 15mm / 0.2 x 0.6in 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 20M 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 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.
