How to avoid motor jamming during operation?

 How to avoid motor jamming during operation? Stuck motor operation will not only affect the normal operation of the equipment, but also may shorten the service life of the motor and increase maintenance costs. In order to avoid the motor running jamming, can be from the motor selection, installation and commissioning, operation and maintenance of a number of links to start.

Before motor selection, the power, torque and speed required for the operation of the equipment should be accurately calculated and other parameters. When driving a conveyor belt, it is necessary to calculate the power and torque that the motor needs to provide according to the length of the conveyor belt, running speed and other factors, to ensure that the rated parameters of the selected motor can meet the actual load requirements.

Different loads have different characteristics, such as constant torque loads, constant power loads and fan pump loads. For constant torque loads, the motor with sufficient torque output capacity should be selected; for fan and pump loads, the use of variable frequency motors can be considered in order to achieve better energy saving effect and operational stability.

The installation accuracy of the motor directly affects its operating performance. Installation should ensure that the coaxiality of the motor and load equipment, to avoid excessive coaxial deviation and generate additional load, resulting in motor operation jamming. When installing the coupling, professional measuring tools should be used for calibration to control the coaxiality error within the allowable range.

The wiring of the motor must be carried out in strict accordance with the wiring diagram to ensure that the phase sequence is correct. If the phase sequence is reversed, the motor may reverse or vibrate or jam. It is important to ensure that the wiring is firm to avoid arcing due to poor contact and damage to the motor windings.

The motor generates heat during operation, and if the cooling system is blocked, it will cause the motor temperature to be too high, affecting its performance and life. The motor’s cooling fan, heat sink and other components should be cleaned regularly to ensure that the heat dissipation channels are clear.

Dust and corrosive gases can cause damage to the motor’s windings, bearings and other components, affecting the normal operation of the motor. Effective protective measures should be taken to reduce the dust and corrosive gases from entering the inside of the motor.

Why don’t all new energy vehicles use the same type of powertrain?

 　　Why don’t all new energy vehicles use the same type of powertrain? The core reason why new energy vehicles do not uniformly adopt a single powertrain is that there are significant differences between different technology routes in terms of performance, applicable scenarios and infrastructure requirements, and companies need to choose the optimal solution based on technical characteristics and market demand. 　　Pure electric vehicles use batteries as the only power source, with a simple structure and outstanding zero-emission advantages, but range and charging time are still bottlenecks. However, performance degradation in low-temperature environments and insufficient coverage of charging facilities still limit their application in long-distance travelling or inconvenient charging areas. 　　Plug-in hybrid vehicles combine a fuel engine with an electric motor to achieve pure electric driving for short distances through external charging, while relying on the fuel engin...

Where does the power for new energy vehicles come from?

 　　Where does the power for new energy vehicles come from? The power sources for new energy vehicles are diverse, primarily including electricity and hydrogen fuel. These energy forms are more environmentally friendly and sustainable compared to the petroleum used in traditional fuel-powered vehicles. 　　Electricity is the primary power source for new energy vehicles. Pure electric vehicles rely entirely on batteries and electric motors for propulsion, without an internal combustion engine. Batteries are charged at charging stations or using home chargers, and electric motors convert electrical energy into power to drive the vehicle. 　　Hydrogen fuel is another important power source for new energy vehicles. Fuel cell vehicles use hydrogen as fuel, combining hydrogen and oxygen through fuel cells to generate electricity. This process only produces water vapour and other harmless by-products. The batteries in fuel cell vehicles utilise this electricity to drive the vehic...
