ASLONG DC Motor JGB37-3530 Problem Solving Guide

1、 Preface

ASLONG DC motor JGB37-3530 plays a key role in many application scenarios with its excellent power output, precise control performance, and high reliability, helping various equipment operate efficiently and stably. However, like all mechanical equipment, it may also encounter some problems during actual use. This article aims to propose effective solutions to these potential issues, ensuring that JGB37-3530 DC motors always maintain optimal working conditions and create sustained value for users.

2、 Common problems and solutions

（1） Unstable motor speed
Problem description: The motor experiences speed fluctuations during operation, which makes it impossible to maintain the set speed value and affects the normal operation of the equipment.
Possible reasons:
Power supply voltage fluctuation: When the voltage is unstable, it can cause changes in the input power of the motor, resulting in unstable speed.
Load variation: When the load exceeds the rated range of the motor or fluctuates greatly, it is difficult for the motor to maintain a constant speed.
Internal faults of the motor, such as worn carbon brushes and local short circuits in the windings, can also affect the motor speed.
Solution strategy:
Stable power supply voltage: To ensure the stability of the motor power supply voltage, a voltage regulator can be used to maintain the voltage within the rated range.
Reasonably control the load: avoid motor overload operation and allocate the load reasonably according to the rated power of the motor.
Inspect the interior of the motor: Regularly check the internal condition of the motor, replace worn carbon brushes in a timely manner, and repair or replace damaged windings.

（2） Excessive motor noise

Problem description: The noise generated by the motor during operation exceeds the normal range, producing a loud noise that affects the working environment and equipment stability.
Possible reasons:
Bearing wear: Excessive bearing wear can cause the motor rotor to operate unstably and produce abnormal noise.
Loose fasteners: The motor casing or internal fasteners become loose, causing vibration and noise.
Abnormal ventilation system: The motor cooling fan or ventilation duct is blocked, causing airflow disorder and noise.
Solution strategy:
Check bearings: Regularly inspect the wear of bearings and replace them with new ones if necessary.
Tightening components: Check the motor housing and internal fasteners to ensure that all components are securely fastened in place.
Cleaning the ventilation system: Clean the cooling fan and ventilation duct to maintain smooth ventilation and reduce noise generation.

（3） Motor overheating
Problem description: Abnormal temperature rise during motor operation may lead to a decrease in motor performance or even damage.
Possible reasons:
Poor heat dissipation: Poor ventilation at the motor installation location or blocked radiator, affecting heat dissipation efficiency.
Overload operation: Long term overload operation of the motor results in excessive current and excessive heat generation.
Internal heat dissipation failure: The internal cooling system of the motor (such as the fan) is malfunctioning and unable to dissipate heat properly.
Solution strategy:
Optimize heat dissipation conditions: Improve the ventilation conditions of the motor installation location, clean the radiator, and ensure good heat dissipation.
Control operating load: Reasonably arrange the working load of the motor to avoid long-term overload operation.
Check the cooling system: Check if the internal cooling system of the motor is working properly, and promptly repair or replace damaged components.

（4） The motor cannot start
Problem description: The motor cannot start and operate normally after being powered on, which may be due to various reasons.
Possible reasons:
Power failure: The power supply is not properly connected, the voltage is too low, or there is an open circuit in the power supply circuit.
Excessive motor load: When starting, the load exceeds the motor's starting torque limit, resulting in the inability to start.
Internal mechanical faults of the motor, such as rotor jamming, gear damage, etc., hinder the normal operation of the motor.
Solution strategy:
Check power supply: Check if the power connection is correct, if the voltage is normal, and eliminate power supply faults.
Reduce load: Check the motor load to ensure that the load is within the range of motor starting torque during startup.
Inspect mechanical components: Check the internal mechanical components of the motor to eliminate any issues of jamming or damage.

3、 Preventive measures and daily maintenance
Regular inspection and maintenance: Establish a regular inspection system to regularly check the wear and looseness of various components of the motor, promptly identify and solve problems, and extend the service life of the motor.

Proper use of equipment: Strictly follow the motor instruction manual to avoid overload and overspeed operation, ensure that the motor operates within the rated parameter range, and guarantee stable operation.

Keep the equipment clean: Regularly clean the dust and debris on the surface of the motor, keep the ventilation openings unobstructed, and prevent dust from entering the interior of the motor and affecting heat dissipation and normal operation.
Monitoring the operating status: If conditions permit, install motor monitoring equipment to monitor the operating parameters of the motor in real time, such as voltage, current, temperature, etc., and promptly detect abnormalities and take measures.
