Key Considerations for Using a DC Motor After 6 Months in Storage

There are considerable impacts associated with long-term storage—six months or longer- upon DC motors, both brushless types like those from Zhengke as well as typical hobby and industrial brush types. Properly handling and maintaining a motor's operation prior to use is crucial to providing optimal performance and durability, regardless of whether the motor is being used in machine tools, robotics, or for home hobbyists building a 12V Dc Gear Motor. Let's look at the proper actions necessary to ensure that the motor continues to operate properly after an extended storage period.

Why Long-Term Storage Affects Your Dc Motors

If you don't use your motors for an extended period of time, the motor will experience problems due to dust settling on critical parts. If you do not regularly lubricate the motors, the lubricants will degrade or evaporate during operation, causing excess friction and overheating of the motors. If you do not run the motors, moisture can accumulate, and rust or corrosion can develop on the motor parts. All of these issues will significantly affect how efficient and safe your motor is as well as its life cycle.

Many owners of small DC motors might not be aware of the potential storage-related risks that can occur until performance problems show up. You can help reduce the likelihood of storage-related issues by preparing for them properly through preventative maintenance.

Essential Steps to Prepare Your Motor for Use

Before turning on a DC motor that has been in storage for six months or more, this quick checklist should be completed. After checking these areas now, it will save you time, work, and/or repair costs in the future.

1. Conduct an External Inspection: Thoroughly check the exterior of the motor for any signs of dirt, damage, or corrosion. Pay attention to the electrical connections, lead wires, and any openings that could allow contamination into the motor. If necessary, use a dry cloth or compressed air to remove dust and/or debris.

2. Address Rust and Corrosion: Rust can be a serious problem when storing motors. If you see rust or oxidation, try to clean it off gently with an appropriate cleaning agent or an anti-corrosion treatment. If left untreated, rust can cause very serious damage as it continues to grow.

3. Check for Adequate Lubrication: Motor lubrication is vital for smooth operation. If a motor has been stored for a period of time, the grease or oil used may have dried out or deteriorated; therefore, to prevent unnecessary wear and tear on all moving parts of the motor, the old lubricant should be cleaned away and replaced with grease recommended by the manufacturer.

With regard to specialized motors such as 12V DC gearbox motors, consideration should also be given to ensuring that the gearbox is properly lubed as well.

4. Test Electrical Components: After connecting all of the wires, make sure that they are properly connected by checking each wire's connection with a multimeter (or other device) for resistance, continuity, and voltage, so you know your brushless DC motor will be able to support its rated load.

5. Perform a Low-Voltage Start: By conducting a test at low voltage to determine any imbalance and/or irregularities in the operation of the motor prior to being run at full power, you will be able to correct smaller issues before they become larger ones.

Pro-Tip: Optimal Storage Practices to Avoid Future Issues

If you expect to store your Zhengke motor or other DC motors, it is very important that you follow the correct procedures for storing them. The motor should be stored in a dry, clean, and climate-controlled environment to avoid dust and moisture from accumulating on the motor. You should protect all open parts of the motor by covering them with an appropriate protective cover so they will not be exposed to contaminants. You may also want to operate the motor for a brief period every two months to keep all of the moving parts functional. By being proactive about these items, you will reduce the potential for damage caused by storing the motor for an extended period of time.

FAQ

1. Will my motor lose efficiency after being stored? If a motor is stored improperly, then the following factors can hinder its performance: degraded lubrication, rust, accumulation of dust. Fortunately, if a motor is regularly checked and properly maintained, then it can be made functional again and will also provide a longer service life for that motor.

2. How do I identify a problem after storage? Be aware of any strange sounds, warmth on your hands, or problems with how the machine is performing in its initial operations will be indications of whether the motor may need repair or an adjustment.
