Micro Coreless Motor product introduction:
Micro Coreless Motor in structure broke through the traditional motor rotor structure, USES is no rotor, also called the hollow rotor cup type.Hollow cup motor with brush and brushless divides into two kinds, brush with hollow cup motor rotor iron core, without brush hollow cup motor stator iron core.Winding adopts delta connection.
Function: fast speed, suitable for aircraft model, electric toothbrush,USB fan and other products.
Characteristic: the volume is 6MM 7MM fast.
Operating temperature range:
Micro Coreless Motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a Micro Coreless Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Hollow cup motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.

The mapping circuit diagram is shown in the attached figure. The power supply uses a self-excited oscillation circuit, and the transformer couples the buck output. After the mains is switched on, the 220V AC is output by D1~D4 bridge rectification and C1 filtering, and then outputs about 260V DC high voltage, and is supplied to the load L1 and b poles of the high voltage switch triode Q via R3 and R5 (b voltage is regulated by the voltage regulator) D5 protection), the Q tube is turned on, and the current generates a pulsed magnetic field through the primary winding L1 of the transformer T. The pulsed magnetic field is coupled to the voltage of <9.5V via L3, and is outputted by D8 rectification and C5 to output a DC voltage of about 8V.
The other way is connected to the negative feedback voltage via L2. The negative feedback voltage is applied to the base of Q through C2, R6, R4 and R5 to make Q cut off. The high voltage DC is turned on by R3 and R5, and the pulse current is output again by L3. A new round of electromagnetic induction causes the L2 negative feedback current to pass through the original path again to make the Q tube cut off. The circuit changes continuously to make the circuit continuously oscillate, and L3 continuously outputs DC power.
When the switching power supply is used to supply power to the 6V small recorder, the output circuit should be serially connected with a 10Ω/8W wirewound resistor and a 1500μF/16V electrolytic capacitor to form a filter and then output power.
Features: small size, fast speed, dc high speed motor starting voltage 0.6v is not possible for other motors.Wear shaking head, strong vibration feeling.
