Item Type: Brushless Motor_x000D_ Model: XD-37GB3650 _x000D_ Material: Copper_x000D_ Output Shaft Size: Approx. 12 x 6mm / 0.5 x 0.2in_x000D_ 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_x000D_ 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._x000D_ 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. _x000D_ Insulation Class: Class B(130)_x000D_ Operating Environment Temperature: Motor: -10~+40 (no icing)_x000D_ Use Environment Humidity: 85% or less (no condensation)_x000D_ CW/CCW: Yes_x000D_ Speed Adjusted: Yes_x000D_ Notes: _x000D_ 1 Overload and Locked Rotor: _x000D_ 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._x000D_ 2 When Running at Low Speed: _x000D_ 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._x000D_ 3 Precautions on the PWM Controller: _x000D_ 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._x000D_ 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)_x000D_ 4 Regarding Inertia and Braking: _x000D_ 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._x000D_ 5 Treatment of Floor Motor: _x000D_ 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. _x000D_ Wiring Method: _x000D_ Red wire: connect to the positive pole of the power supply_x000D_ Black wire: connect to the negative pole of the power supply_x000D_ White wire: empty (turn CCW)_x000D_ Red wire: connect to the positive pole of the power supply_x000D_ White wire and black wire: connect the negative pole in parallel (CW)_x000D_ Blue wire: PWM speed control line, connected to 0-5V pulse width speed controller_x000D_ Yellow wire: FG signal line outputs Hall signal, the basic pulse is one signal six circles _x000D_ ModelVoltage(DC/V)No-Load Speed(rpm/min)No-Load Current(A)Load Speed(rpm/min)Load Torsion(kgf/cm)Power(W)_x000D_ XD-37GB3650121000.1580812_x000D_ 2000.131604.88_x000D_ 3000.112403.56_x000D_ 5000.14001.95_x000D_ 6000.154801.95
