Detection of new energy vehicle drive motor (1) - motor stator

Detection of new energy vehicle drive motor (1) - motor stator

The drive motor detection of new energy vehicles is divided into three parts: drive motor stator, cast aluminum rotor and motor complete machine. This paper mainly introduces the method and process of using motor detection equipment to detect new energy drive motor stator. The new energy vehicle drive motor stator testing equipment adopts the clamping testing method, one-time wiring, and one-stop complete performance testing. The testing results are displayed on the screen, and the product performance can be seen intuitively.

Internal detailed explanation of new energy vehicle motor controller

Internal detailed explanation of new energy vehicle motor controller

The motor controller is an energy transmission device between the power battery and the motor, which is mainly composed of a power supply circuit, a control circuit and a drive circuit. The function is: to receive the VCU command, invert the DC power provided by the power battery into three-phase AC power to drive the motor; during braking and deceleration, rectify the AC power from the motor into DC power to charge the power battery. The motor controller ensures the normal forward, backward, stop, energy recovery, communication, fault detection and alarm of the vehicle, and is an important component of the electric vehicle.

What are the performance requirements for electric vehicle motors

In this era of increasing traffic flow, the main function of electric vehicle motors is to generate driving torque. As a power source for electric vehicles, what are the performance requirements of electric vehicle motors? Cars need high torque at low speeds or when climbing hills , when driving at high speed, low torque is required. The main requirements that electric vehicle motors should meet can be summarized into the following 10 aspects: 1. High voltage Within the allowable range, use high voltage as much as possible, which can reduce the size of the motor and the wire In particular, the size of the equipment can reduce the cost of the inverter. The working voltage is increased from 274V of THS to 500V of THSB;

Winter car is just a skill inventory: car motor articles

Winter car is just a skill inventory: car motor articles

The temperature in the morning and evening in winter is very cold, and you need to maintain your car to ensure normal driving. The following 18 years of automotive motor manufacturers teach you how to maintain the motor and motor used in winter vehicles. Winter car motor maintenance When using the battery to start in winter, use the starter without interruption, which will cause the battery to damage the car motor due to excessive discharge. The correct method is: the time for the vehicle to start at a time is preferably controlled within 5 seconds, that is, turning the key or pressing the start switch does not last for too long. If the startup fails 3 times, it should be stopped for a few minutes and then restarted, so as not to damage the battery. Normal battery life is 4 years
