VS-XXXX-031 series speed encoder for railway locomotives

I. وصف

The speed encoder of rail transit traction motors features stable performance, high sensitivity and high reliability. This product can be widely applied to the speed measurement system of traction motors in the field of rail transit. It is used in large motor power equipment such as high-speed railway vehicles, mainline locomotives, and metro vehicles, replacing the Yuchuan passive speed sensors TS5840N581, TS5840N series and TS5841N series speed sensors. From intercity high-speed railway vehicles and metro locomotives to the Harmony and Fuxing high-speed railways, they are all applied in high-speed vehicles between cities and urban subways every day. They are used in the CRH2 type high-speed railway vehicles and CRH3 type high-speed railway vehicles of China North Railway Corporation, various heavy-haul mainline locomotives of China North Railway, and metro vehicles produced by Qingdao Sifang Locomotive Factory.

The speed encoder for railway locomotives adopts the principle of magnetic induction to monitor the speed regulators of large and medium-sized asynchronous motors

Based on over 20 years of application experience and achievements, continuous technological innovation and development, the powerful CNC processed integrated alloy housing, excellent anti-interference, anti-surge and anti-vibration performance, as well as resistance to instantaneous high and low temperature changes, dust-proof, water-proof and oil-proof IP68, and self-healing speed signal technology, with tens of thousands of sets per day worldwide, is safe and reliable.

2. The MEVS-XXXX-031 railway locomotive wheel set magnetoelectric velocity sensor is a type of velocity sensor used to measure the speed of train wheel sets. It is installed above the gear under test at the axle end of the locomotive and outputs a single-channel square wave signal proportional to the train speed. This sensor features high reliability and strong anti-interference ability.
