Differentiation of deceleration starter stator and permanent magnet starter stator from China starter stator manufacturers
Differentiation of deceleration starter stator and permanent magnet starter stator from China starter stator manufacturers.
Deceleration starter and permanent magnet starter have the following differences.
| Retarding starter | Permanent magnet starter | |
| Structural principle | There is a gear reducer between the electric pivot and the drive gear, and the common gear reducer forms are external meshing type, internal meshing type and planetary gear type. When working, the electromagnetic switch is first switched on to make the motor electrified to rotate, and then the high-speed rotation of the motor is converted into the output of low speed and high torque through the reduction gear system, which drives the engine flywheel rotation to start the engine. | With permanent magnet material as the magnetic pole, the excitation winding and magnetic pole core in the traditional starter are eliminated. When working, when the driver presses the start button, the current passes through the permanent magnet coil to generate a magnetic field, and the permanent magnet itself also generates a magnetic field. The two magnetic fields interact, making the driving gear of the starter engage with the flywheel of the engine, transmitting mechanical power and starting the engine. |
| Performance characteristics | Through the gear reduction mechanism, a larger torque output can be obtained under the smaller motor volume and power, so as to start the engine more effectively, and because of the use of high-speed low-torque motors, the current consumption of the motor is reduced, and the burden on the battery is less. | Because of the elimination of the field winding and magnetic pole core, the structure is simple, the volume and mass are greatly reduced, and the reliability is improved. At the same time, the magnetic field generated by the permanent magnet is stable and powerful, which can achieve rapid and efficient mechanical transmission when starting, and the starting speed is fast and the efficiency is high. |
| Application scenario | Suitable for all types of vehicles and engines, especially for high-power engines that require greater torque to start, internal meshing and planetary gear reduction starters can better meet the needs. In addition, in some vehicles with high space requirements, the deceleration starter is also widely used because of its compact structure. | It is often used in small cars, motorcycles and some vehicles with strict requirements on the volume and weight of the starter, such as electric vehicles and hybrid vehicles. Due to its fast start speed and high efficiency, it is also suitable for vehicles that need to be started frequently. |
China starter stator manufacturers share the difference between deceleration starter stator and permanent magnet starter stator.
| Decelerating starter stator | Permanent magnet starter stator | |
| Structural composition | It is usually composed of a convex pole core and an exciting winding. The core is generally made of silicon steel sheet laminated to reduce hysteresis loss and eddy current loss. The field winding is made of insulated copper or aluminum wire wound on an iron core. | It is mainly composed of a stator core and a stator winding. The stator core is also made of laminated silicon steel sheet with good magnetic conductivity, and the stator windings are generally made of multi-layer insulated wires to reduce the risk of short-circuit between turns. |
| Magnetic field generation mode | It is necessary to pass direct current into the field winding, and a magnetic field is generated when the current passes through the winding. | Its magnetic field is generated by permanent magnets, which are pre-magnetized at the time of manufacture and installed on the stator to establish a magnetic field in the space around it without the need for external energy. |
| Working principle | When the excitation winding is energized, the generated magnetic field interacts with the armature winding on the rotor, causing the rotor to rotate. Due to the high speed and low torque DC motor, a gear reducer is installed between the pivot and the drive gear to reduce the motor speed and increase its torque. | After the stator winding is energized, a rotating magnetic field is generated, which interacts with the magnetic field generated by the permanent magnet on the rotor to make the rotor rotate. Because the magnetic field generated by the permanent magnet is stable and powerful, rapid and efficient mechanical transmission can be achieved when starting, and the starting speed is fast and the efficiency is high. |
| Performance characteristics | At the same power, the volume and mass are relatively large, but the larger torque output can be obtained under the smaller motor volume and power through the gear reducer, so as to start the engine more effectively, and because of the use of high-speed low-torque motor, the current consumption of the motor is reduced, and the burden on the battery is less. | Due to the cancellation of the field winding and magnetic pole core, the structure is simple, the volume and mass are greatly reduced, the reliability is improved, and the high torque can be quickly reached at the start, the operating performance is more stable, has a high overload capacity, and also reduces the size and weight of the motor. |
