Electric treadmill is a common fitness equipment in gyms and homes. It drives the running belt through a motor, allowing people to passively run or walk at different speeds. The motors used in electric treadmills are DC motors and AC motors, so which one is better for these two types of motor treadmills, and what is the difference?
At present, all household electric treadmills on the market are DC motors, but DC motors are not as durable and safe as AC motors, which means that AC treadmills will dominate the market in the future. If the commercial electric running runs continuously for a long time in the club, then you must buy an AC treadmill. The AC motor electric motor has a frequency converter, while the DC motor does not need a frequency converter. At present, the household electric motor on the market is a DC motor. The DC motor is not as durable as the AC motor, and the cost of the DC motor is relatively low.
DC motor:
1. The national implementation standard stipulates that the service life of the DC motor is 2000 hours.
2. DC motor carbon brushes have a service life of 500 hours and need to be replaced once.
3. The continuous use of the DC motor will cause the carbon brush to heat up and generate carbon deposits, which is easy to leak.
4. If the DC motor is used continuously for too long, it will cause: a. Generate a large current, the motor is hot, and even burn the power board; b. It is prone to overcurrent protection and automatic shutdown.
AC motor:
1. The AC motor is equipped with a frequency controller, and there is an error display window, which will automatically detect the fault and display the corresponding code, so that any problems will be clear at a glance.
2. Compared with a DC motor, the output power of an AC motor with the same number of horses will be greater than that of a DC motor.
3. The AC motor does not have carbon brushes, so it will not produce the drawbacks of the DC motor.
