Faced with bottlenecks, ball bearing manufacturers rely on price increases to improve quality and stabilize revenue. The secondary market has two fixed rollers as rolling guides. Due to the synchronous sliding shoe wheel applying pressure to the guide rail, as the guide rail conveyor mechanism moves, the ball is accurately output to the supply system at any time. As the positive current conductor rotor of the collector (centrifugal guide rail) and its rotating ring tilt relative to the guide rail [optimal].

The Intel JN-001 inverter clamp type 32-bit rectification device also has a feedback link and needs to transmit background signals.

Xi'an Xima JS-3 often observes whether there are changes in the force display, and if there are any changes, they should be reported in a timely manner.

The initial installation of W1 is due to three-phase load imbalance, and the single-phase no-load current changes correspondingly with time/current, otherwise it may cause motor overload and damage.

● External observation method. Observe whether the terminal box and winding ends are burnt, and if the winding overheats, it leaves a dark brown color and a foul odor.

● Temperature detection method. Run without load for 20 minutes (stop immediately if any abnormalities are found), and touch the back of your hand to see if all parts of the winding exceed the normal temperature.

● Electrification experiment method. Use a Ammeter to measure. If the current of a phase is too large, it indicates that there is a short circuit in the phase.

● Multimeter or megohmmeter method. Measure the insulation resistance between any two phase windings. If the reading is very small or zero, it indicates a short circuit between the two phase windings.

● Voltage drop method. After connecting the three windings in series, a low-voltage safe AC current was applied, and the small reading group was found to have a short circuit fault.

● Current method. When the motor operates with no load, first measure the three-phase current, and then measure and compare the two phases. If it does not change with the power supply exchange, one phase winding with large current has a short circuit.

The short circuit point is at the end. Insulating materials can be used to separate short circuit points, or insulated wires can be repainted and then repainted and dried.

● Short circuit inside the wire slot. After softening it, identify the short circuit point and repair it. After reinstalling it in the wire slot, paint and dry it.

For each phase winding with less than 1/12 turns on the short circuit, when the number of turns is connected in series, cut off all short circuits and connect the conductive part to form a closed circuit for emergency use< Eod>.
