Pwm circuit boards

Great Technology Bringing you the Pulse Width Modulation Circuit Board to Improve Treadmills

A relatively new electronics technology called PWM (pulse width modulation) is used on many high-quality treadmills. This technology was first used in the mid-90's. The advantages of PWM include: more power; quiet; low amp draw; lower cost; smaller flywheel; and lower circuit boards.

The pure voltage of this technology creates more power. The PWM, as well as SCR control boards take AC power and can change (correct) it into direct current (DC) voltage. Whereas AC voltage constantly changes (or chops) positive/negative current 60 times a second (60 cycle), PWM boards chop positive/negative current 1200 times per second. The motor can visualize strong current due to its pure DC voltage.

Because the DC voltage is pure, there is no need to filter out an electrical humming sound. That is why a treadmill with PWM is much quieter than those with other circuit boards. This also results in less amp draw.

When there is a high amp draw, a breaker is more likely to blow. With PWM it provides more acceptance of heavy weight because of a lower amp draw.

Smaller flywheels can be utilized with PWM because the motor is giving and receiving more energy due to PWM's pure energy. A large flywheel is not necessary to maintain tread belt movement. This provides lower energy costs, even though PWM circuit boards are more expensive to produce; however, your overall savings are greater.

Circuit boards will continue to get smaller and more reliable as this PWM technology develops even further. This will provide even smoother fitness and more reliability. With the more advanced circuit boards available today, the circuits and diodes are encased in a steel casing. This prevents dust, dirt and heat from entering which can cause circuit failure.

Treadmills contain different types of frames such as welded, bolted; steel and aluminum.

The drilled holes on a bolted frame are larger than the diameter of the bolt. This leaves room for movement, but over the long haul, it creates fatigue, and sometimes failure, of the frame.

Aluminum frames are more expensive than steel and cost more to weld than steel frames, however, both types are very durable.

The types of elevation motors that have the longest lifespan and are most efficient are called worm-gear actuator driven electronic elevation motors. These worm-gear systems use an individual motor which is very powerful and elevates the treadmill while it is being used. These types of motors normally have a thrust value of 400 to 100 pounds. This enables you to exercise without the deck stopping or hesitating.
