FAQ:
Q: Can we customize the product electromechanical solutions?
A: Of course, we have professional engineers to provide you with solutions as client's size and specs requirments.
Q: How long is the delivery time of the product?
A: Generally speaking, the sample order needs 7 days after the specification approved by client, Bulk order needs 1 months, the repeat order could by shipment within 10-20days.
Q: Before the sample making, What parameter should I provide before the sample making?
A: We need to know the Nominal Voltage, Free-load and on load peformance, Rotation Direction, Shaft Diameter and Length. If there is other special requirement, please let us know in advance such as working current limits, EMC limits, noise limits, expected life time.

The Advantage Of DC Motor
DC motor is a type of motor that converts electrical energy into mechanical energy, and its working principle is based on electromagnetic induction and Lorentz force. A DC motor consists of a stator and a rotor, with the stator stationary and the rotor rotatable.
In a DC motor, there is a set of coils on the stator, called excitation coils, which are connected to the power supply to generate a combustion field. There is also a set of coils on the rotor, called armature coils, which are connected to the power supply to generate current. When the current passes through the central coil, it generates a magnetic field that interacts with the magnetic field of the excitation coil, generating a torque that causes the rotor to start rotating.
When the rotor rotates, the direction of the current in the armature coil will change accordingly, which will cause the direction of the magnetic field to also change. Due to the Lorentz force, this changing magnetic field will generate a reverse torque, causing the rotor to slow down and ultimately stop rotating. In order to maintain the motion of the rotor, it is necessary to continuously change the direction of the current in the armature coil, which is called commutation.
Characteristic
1.Compared with the LDO of linear regulators, high efficiency is a significant advantage of DCDC. Usually, the efficiency is above 70%, and the high efficiency can reach over 95%.
2. Adapt to a wide voltage range.
Classification
In switching DC-DC converters, transistors operate as switches, which means they consume much less power than transistors operating as current dependent sources. When a transistor conducts high current, its voltage drop is very low, while when a transistor conducts high voltage drop, its current is almost zero. Therefore, the switching mode converter has low conduction loss and high efficiency, usually above 80% or 90%. But at high frequencies, switching losses can reduce efficiency, and the higher the switching frequency, the higher the power.
