"The micro gear reducer can provide large torque output and is widely used in various electric products. So what types of DC motors can the micro gear reducer be matched with? The following is a brief description."
Micro gear reducers commonly used motors include brushless DC motors, brushed DC motors, stepper motors, hollow cup motors, etc. as drive motors. DC motors have small specifications, low voltage, low energy consumption, and high output speed.
Brushless DC Motor
This kind of DC refers to a DC motor without brushes and commutators. In addition to the motor armature and permanent magnet part outsourcing, it also has a Hall sensor. This DC motor has low noise, high speed and long service life, but the cost High and complex control methods;
2. Brushed DC motor
A brushed DC motor is a motor with a brush device and a commutator. The brushes are used to introduce or extract DC voltage and current. The brushed DC geared motor has the advantages of fast starting, smooth speed regulation, simple control method, and low cost. The basic structural components of the brushed DC motor include stator, rotor, brushes, and commutator. The interaction between the stator and rotor magnetic field drives the DC motor. Rotating, DC motor stator magnetic field is generated by magnets or stator windings;
3. Stepper motor
A stepper motor is a DC motor that converts electrical pulse signals into corresponding angular displacements. When a pulse signal is input, the rotor will rotate by an angle, the output angular displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. The biggest difference between the incoming motor and other DC motor control is that it receives digital control signals and converts it into angular displacement, and can input a pulse signal for open-loop position control to obtain the specified position increment. The incremental position control system is in phase with the drive DC control. Significantly lower than the cost;
4. Hollow cup motor
The hollow DC motor is small in size, light in weight, high in precision, and high in efficiency. It has outstanding energy-saving and stable characteristics. The rotor structure of traditional DC motors, which is a breakthrough in structure, adopts an ironless rotor. Because the rotor is similar to a cup, it is also Called the hollow cup rotor, the hollow cup rotor completely eliminates the loss caused by the eddy current formed by the traditional iron core rotor. The hollow cup motor can also be divided into two types: brushless and brushed. The rotor of the brushless hollow cup motor has no iron core, and the stator of the brushless hollow cup motor has no iron core.
