What are the Key Advantages of the 10mm Precious Metal Brush DC Motor?

The 10mm Precious Metal Brush DC Motor utilizes precious metal alloy brushes and a precision commutator, with diameters strictly controlled to metric standard dimensions. The motor core comprises a rare earth permanent magnet stator, a three-layer insulated wound rotor, and gold-plated commutator segments. The brushes are made of a palladium-iridium alloy composite. The operating mechanism is based on the law of electromagnetic induction, converting electrical energy into directional torque output through the brush-commutator system. The fully sealed structure meets dust and water resistance requirements and operates at temperatures spanning the industrial range.

Product Advantages

1. The palladium-iridium alloy brushes reduce contact resistance by a specific percentage, suppressing commutation sparks to a safe threshold. Precision rotor dynamic balancing controls vibration levels, and pre-lubricated bearings ensure a maintenance-free operating cycle.

2. The 10mm Precious Metal Brush DC Motor's fully sealed housing is IP54 certified, and the starting torque reduction rate at -40°C is ≤ a specific value. Electromagnetic compatibility meets EMC standards for medical devices, eliminating the risk of interference from brushless motors. 3. Mechanical time constants are as low as milliseconds, with zero overshoot in step response. Torque linearity error is controlled within a specific range, making it suitable for precision speed control systems.

Maintenance Methods

1. Back-purge the commutator slots with compressed air. Do not allow organic solvents to come into contact with the 10mm Precious Metal Brush DC Motor seal. Visually inspect brush wear through a window. If the remaining thickness reaches a critical value, the entire set must be replaced.

2. If rotor eccentricity exceeds tolerance, repair with a laser aligner. Abnormal bearing noise indicates grease drying, requiring hot air replacement. Test coil insulation with a 500V megohmmeter. If the resistance is below the safety threshold, return to the factory for varnishing.

Do precious metal brushes require regular replacement?

Under normal operating conditions, their lifespan exceeds that of ordinary carbon brushes by a certain multiple, and the wear rate is proportional to the square of the current. It is recommended to check the thickness every specified hours and replace the brush spring when a certain percentage remains.
