Warranty Policy of Toan Phat's Motors

Toan Phat Mechanical Co., Ltd. is responsible for the warranty of electric motors manufactured by the company under the condition that users operate and maintain them properly.

1. Warranty Coverage

Toan Phat Mechanical Co., Ltd. commits to repairing any technical defects in the motors free of charge if the errors are due to manufacturing errors.

The following conditions are not covered under the warranty:

 

No.	Errors Details	Image
1	Three-phase Electric Motor (Y) 220/380V: If one phase of the power supply to the motor is lost, the remaining two phases become overloaded, leading to burnout ( as shown by the arrow in the image).      Cause of phase loss: Due to blown fuses, contactor points, circuit breakers, poor contact (loose connection), or loose 3-phase terminal connections.
2	Three-phase Electric Motor (Δ) 380/660V:  If the power supply to the motor experiences a phase loss, one winding phase, powered by the remaining two phases, becomes overloaded, which can result in damage or burnout (as indicated by the arrow in the accompanying image).      Causes of phase loss: This can occur due to blown fuses, faulty contactor contacts, circuit breaker (MCB) issues, poor connections in switches (loose or oxidized contacts), or loose connections in 3-phase terminals.
3	Three-phase electric motors can burn out due to heavy load, exceeding the rated current (as specified on the nameplate), or high ambient temperatures. Additionally, low or high voltage can cause overloading of the motor (as shown in the accompanying image).
4	For bearings, lubrication is extremely important: For equipment safety, it is recommended: If the motor makes unusual noises, the bearing cover should be removed for cleaning, or after 3000-5000 hours of operation, heat-resistant grease should be added (the amount of grease should occupy 2/3 of the bearing space). Early bearing failure is often due to water ingress during use, using incorrect or unsuitable lubricants. Bearings that are not properly lubricated will fail much faster than their expected lifespan.

 

Other causes:

• Water immersion leading to water ingress in the motor, or damage caused by fire.
• Damage to motor components due to improper installation, operation, or accidental drops.
• Running the motor with a variable frequency drive (VFD) at low frequencies without an external forced cooling fan, resulting in overheating.
• Excessive distance between the motor and the VFD (>10m), leading to overvoltage on the motor and insulation damage.
• Components wearing out over time due to natural wear and tear.
• Replacement parts or components not supplied by the company being used in the motor.

2. Warranty Period

• The warranty period is 1 year with product replacement (the duration is indicated on the product label).

3.  Non-Warranty Repairs

• Any damage caused by repairs or adjustments not performed by the company.

• Using the motor outside the guidelines provided in the user manual (voltage, current, load), leading to damage from excessive use.

• Any modifications or alterations from the original design causing damage.

• Rust, paint discoloration, or natural wear and tear of parts over time.

• Damage caused by natural disasters, storms, floods, fire, or other acts of nature.

• Parts damaged due to prolonged storage, such as rubber aging (dust seals) or deteriorated lubricants.

4. Customer Rights and Obligations

To ensure the safe and durable use of the motor, regular inspection and maintenance are essential. Please pay attention to the following points. Failure to adhere to these may result in the denial of warranty repair:

• Operate the electric motor according to the methods outlined in the user manual.
• Conduct "pre-operation checks" as specified in the user manual.
• Perform periodic inspections on schedule as indicated in the electric motor user manual.
• Replace and add grease to the bearings in accordance with the instructions provided in the user manual.
