WEG 3-Phase 5HP Motor
WEG̵7;s three-phase, 5-horsepower general purpose motor is commonly used in fans, crushers, pumps, centrifugal machines, elevators and woodworking tools. This three-phase, alternating-current power system is more economical than other types of motors and uses a circuit-conducting system that carries three currents that peak at different times. The motor generates an output of 5 horsepower and has a corrosion-resistant finish that is suitable for dirty, dusty and non-hazardous environments. The motor costs around $600.
Possible Repairs
WEG three-phase, 5-horsepower motors are sturdy, but they may break down due to fluctuations in the AC power supply or regular wear and tear associated with overuse. Lack of lubrication or exposure to water can disrupt the bearings of your three-phase motor. Regular care of the bearings is essential for longer life of WEG three-phase, 5 horsepower motor.
Cost Plan
The cost to repair your WEG three-phase, 5-horsepower motor may vary depending on the underlying problem. Lubrication may be an easy and low-cost way of maintaining motors and improving their productivity, says Marek Lukaszczyk of WEG Electric Motors. Grease can reduce friction and protect the bearings against corrosion. A 16-ounce can of lubricating grease may cost around $5 to 15, depending on the manufacturer. The amount of grease you need during one application can be calculated by multiplying the outer bearing diameter, the bearing width and .005. It is important not to over lubricate the bearing.
Bearings
If the bearing is completely worn out, replacing it may be the only option. If you are good with machines and can replace the bearings yourself, you may purchase the bearings at a local hardware store. The motor consists of many bearings, which may cost about $15 to $25, in general. If you need technical assistance to replace the bearings, the mechanic may charge $80 to $100 per hour for the work. Replacing other parts of WEG three-phase, 5-HP motor may be more expensive. It may be cheaper to buy a new motor instead.
Tips
According to Perry̵7;s Electric Motors and Drive Sales, it may not be economical to repair motors with less than 5 horsepower unless the repairs are minor. It is important to diagnose the issues associated with your WEG three-phase, 5-horsepower motor before starting any repairs. Seek professional help to diagnose the problem and estimate the cost. Some technicians may provide free estimates while others may charge an hourly rate to diagnose the problem. You may also contact the helpline provided by WEG Electric Corp for estimates.
