Submersible motors are a vital part of water systems, especially for irrigation and household water supply. However, one common issue faced by many users is the frequent burning of these motors. This can be frustrating and costly, especially if you have invested in a high-quality motor. In this blog, we will dive into the most common reasons why your submersible motor might be burning out and provide practical solutions to prevent it. Plus, we’ll introduce an advanced solution from BTCO Starters to ensure your motor’s safety and longevity.
1. Common Causes of Motor Burnouts
a) Voltage Fluctuations
One of the primary reasons for motor failure is voltage instability. If there are significant fluctuations in the high tension (HT) or low tension (LT) sides of your power line, your motor is likely to burn out. The drastic changes in voltage can overload the motor, leading to severe damage.
Solution: Install a high-quality starter with built-in voltage monitoring to detect and protect against these fluctuations. A microcontroller-based starter like BTCO MPAU can automatically stop the motor when abnormal voltage is detected, preventing potential burnout.
b) Bush and Bearing Issues
Wear and tear of internal components, especially the bush and bearing, can lead to motor failure. If the bearings are not lubricated properly or have worn out, they can cause excessive friction and heat, resulting in motor burnout.
Solution: Regular maintenance and inspection of the motor’s mechanical parts can prevent this issue. Using BTCO starters with advanced monitoring can help detect abnormal current patterns, which often indicate mechanical problems before they become severe.
c) Pump Jamming Due to Debris
Dirt, mud, or small stones can easily jam the pump if the water source is not clean. This obstruction can increase the load on the motor, causing it to overheat and burn out.
Solution: Install a filter to reduce the amount of debris entering the motor. Additionally, using a smart starter like the BTCO MPAU with overload protection can help detect jamming and automatically shut off the motor to prevent damage.
d) Ineffective Thermal Relay Starters
Traditional starters often use thermal relays for overload protection, but these devices are not always accurate. They may fail to detect subtle changes in motor current or voltage, resulting in delayed response times and motor burnout.
Solution: Opt for microcontroller-based starters that use digital sensors for accurate detection of voltage, current, and other parameters. BTCO Starters offer precise digital monitoring to ensure the motor is protected in real-time.
e) Running the Motor Without Proper Three-Phase Current
Submersible motors designed for three-phase power should not be run on single-phase power. However, in areas where three-phase power is not available consistently, some users manually add capacitors to make the motor run. Incorrect capacitor installation or faulty starters can lead to imbalanced currents and motor damage.
Solution: Invest in a smart starter like BTCO MPAU, which automatically manages capacitors and ensures balanced power delivery to the motor, preventing potential burnouts.
f) Dry Run Scenario
If the borewell runs dry or there is insufficient water, the motor continues running without load, leading to overheating. Many traditional starters do not have the capability to detect this dry run scenario.
Solution: Use a starter with dry run protection. BTCO Starters come equipped with sensors that detect the water level in the borewell and shut off the motor if it runs dry, thus preventing damage.
2. Advanced Solutions by BTCO Starters
At BTCO, we understand the challenges faced by users with their submersible motors. We have designed our products with advanced features to address all the above scenarios, ensuring the safety and longevity of your motor.
Microcontroller-Based Starters:
All BTCO starters are equipped with microcontrollers for precise monitoring of motor parameters like voltage, current, and water level. This digital approach ensures accurate detection and response, unlike outdated analog systems.
Automatic Voltage and Current Monitoring:
BTCO Starters continuously monitor voltage and current. In case of any fluctuations, the motor is automatically stopped to prevent damage.
Dry Run Protection:
Our starters can detect when the borewell runs dry and stop the motor immediately, preventing overheating and burnout.
Overload Trip Setting:
We have built-in overload protection to detect if the motor is under excessive load. The starter automatically trips in such cases to prevent motor burnout.
Automatic Capacitor Management:
For three-phase motors, our advanced starters manage capacitors automatically. This eliminates the need for manual intervention and ensures the motor receives balanced power, reducing the risk of burnout.
