Unlike the pre-set speed control, variable control allows a greater variation in motor speeds. The motor is a plain AC series-wound brush motor and consequently it is incapable of any variation in speed on its own.
Speed is governed by a separate speed control unit. This unit consists of a printed circuit board with a number of solid-state components, often called the speed module or motor control module. In simple terms, this device interrupts the power supply to the motor at regular intervals. In effect, it pulses the motor. If the pulsing is increased, the motor will run faster and if pulsing is slowed, the motor will run slower. Read the rest of this entry »
The electric food mixer is truly a labour-saving appliance. Many variations can be found from the simple hand-held type to the large table-top version with additional attachments, such as juice extractor, liquidizer, vegetable peeler, can opener and grinder.
At the heart of all mains powered mixers is a series-wound brush-gear motor. This type of motor is used because of its good power output (up to 3hp on large table-top models) combined with the capacity for variable-speed control. These two advantages make this aversatile appliance. Read the rest of this entry »
The brush roll is supported on bearings at each end so the barrel rotates freely. Types of bearings, barrels and brushes differ from model to model as well as between manufacturers. Some manufacturers supply individual parts for the brush roll, such as brush strips, bearings and barrel; others supply only complete assemblies. The brush roll on some models may have removable brush strips, whereas others may be a solid brush roll of wood or plastic with fixed brushes. A small selection is shown here to highlight the differences. Read the rest of this entry »
The aim of this manual has been to assist in the D-I-Y repair of your household appliances. I hope that you will now not only possess a greater understanding of how your appliances work, but also the knowledge to prevent many faults from occurring.

Major home appliances are a great investing. A brand new washer can be anywhere from hundreds of dollars to over $1,000; the price of a new refrigerator tops away at over $2,000. And they’re non items you can make without, and then when a convenience breaks, you need to either repair it or change it as quickly as potential.
“If a leading gadget is little than 10 years older, it’s a better wager you can fix it and have much consumption out of it,” says Kaman, president of Appliance Parts Pros. His party’s Web place provides homeowners a resource for finding new equipment maker (OEM) parts for all leading appliances and gadget manufacturers so they can have their damaged appliances backwards upward and running rapidly and little expensively by doing the repairs themselves.
