Vacuum Motor

A: You'll know if your vacuum's motor is burnt out if you're experiencing a complete loss of suction power, unusual noises, or the motor failing to start. You may also notice a burning smell coming from the vacuum. In this case, it's best to stop using the vacuum immediately and have it inspected by a professional.

A: It could be that your vacuum has no suction because certain parts are obstructed, damaged or worn out. Clogged brush rolls and filters, loose or broken belts, and torn dust bags can all contribute to this problem. Another factor to consider is whether the seals and gaskets have gaps or cracks.

A: The electric motors used in vacuums range from less than 1 HP up to 6 HP. As a general rule, the higher HP a motor is rated, the more load it can handle before it burns out. This makes HP a good way to gauge the strength and reliability of a vacuum cleaner but doesn't really help assess how strong it will be.

A: When the airflow in your vacuum is blocked by a clog, the motor has to work harder to compensate. Over time, this extra strain can lead to overheating and burnout.

A: All breather drains are to be fully operable while in storage (drain plugs removed). The motors must be stored so that the drain is at the lowest point. All breathers and automatic "T" drains must be operable to allow breathing and draining at points other than through the bearings around the shaft.
