Voltage 110/220V AC Speed Control Motor JSCC 90YT90GV22 Variable
Speed Ac Motor
1 . Descriptions:
Today, AC motors are extensively employed in various industries due
to their versatility and efficiency. As their name suggests, these
motors convert electrical energy from an alternating current source
into mechanical energy, resulting in shaft rotation.
AC motors provide numerous benefits compared to their direct
current counterparts. Unlike DC motors, AC motors do not require
brushes or commutators, making them more cost-effective,
straightforward, and reliable in generating mechanical energy.
However, an ongoing challenge associated with AC motors is
achieving precise speed control.

3 . How to control the speed of an AC motor:
An AC motor operates by generating a rotating magnetic field within
its coils, which is transmitted to a rotor connected to an output
shaft. This rotor, in turn, generates a secondary magnetic field
that induces the rotation of the output shaft at a constant speed.
The synchronous speed of the motor can be estimated using the
formula:
Synchronous speed (in revolutions per minute) = (120 * f) / P
Where:
f = Incoming line frequency
P = Number of poles in the motor
For instance, in the United States, where the incoming line
frequency is typically 60 Hz at 120 V, an AC motor with two poles
(a pole pair motor) would have a synchronous speed of 3600
revolutions per minute. In practice, however, the motor operates at
a speed lower than 3600 rpm, and the difference in speed (usually
expressed as a percentage) is known as the slip.
If there is a requirement to achieve lower output speeds using the
same motor, engineers need to control the incoming line frequency
since the number of poles in a typical AC motor remains constant.
This speed control can be achieved using a variable frequency drive
(VFD), which enables engineers to adjust the frequency of the power
supply to the motor.
