Omega is the symbol of the unit of resistance, ohm. Look for the capital Greek letter, Omega to locate the resistance setting. Step 2: Set the multimeter to resistance. Step 1: Switch on the digital multimeter. You need a digital multimeter to do that.

How to conduct the motor winding resistance testĬhecking the motor winding resistance is a straightforward process. A digital multimeter is ideal for measuring the winding resistance of a motor To ensure the motor operates to its best potential, you must know how to measure motor winding resistance regularly. Only at this resistance, the right amount of current is allowed to pass through the coil. The manufacturer gives this particular resistance value. The motor operates correctly when the coil wire has a specific, predetermined resistance. This magnetic field is responsible for the rotation of a metal bar inside the coil. An electric current passes through the wire and induces a magnetic field inside the coil of the wire. An electrical motor contains a wire wrapped around a cylindrical shaft. To understand the concept of motor winding resistance, you must see how the motor works. Most modern cars use a 3-phase induction motorģ-phase induction motor winding resistance Here is a guide on motor winding – how it works and how to check the winding resistance of a 3-phases electric motor. Motor winding resistance test determines motor problems with car battery performance that other tests fail to perceive. If you are facing any motor-related problem such as poor connections, fully or partially shorted coils, incorrect coil connections and imbalance between phases, you should run a motor winding resistance test on your vehicle.
The purpose of a motor in a car is to convert electrical voltage and current into mechanical energy.
