Speed Control Motor

AC Speed Control Motor

1. Structure of Speed Control Motor

Description

The speed can be set broadly(50Hz : 90~1400rpm, 60Hz : 90~1700rpm) with Speed controller.
Speed of the motor is sensed by feedback of T.G which is internal in the Speed Motor.
    Depending on frequency, the number of rotation is not changed.
 ③ Speed Control Motor can be used with Induction, Reversible, Brake, Clutch Brake Motor.

Brake Motor

Today I explain what is AC Brake Motor.

1. Structure of Brake Motor


Brake attached to the rear motor can maintain the load, when power is off.
It is optimal for emergency brakes and vertical load applications when power source is off.
The frequent and instantaneous directional changes are possible. It is possible to make 6 stops per minute with more than 3 seconds of stoppage. 
The Motor and brake use the same power source.




2. Section View of Brake Motor


FEATURES* 
The brake is activated when the power source is turned off.
Shorten overrun. (Overrun times: 2~4 times)
HOLDING TORQUE (0.5~10 kgfcm)
Overrun can shorten by 1~2 times when choosing 
Electromagnetic brake.

Reversible Motor

Last time I introduced Induction Motor.

Induction Motor is a basic motor in all kinds of AC Motor.
But if you want a function of changing running direction with economic price, I can recommend you the Reversible Motor.

This is the structure of Reversible Motor.


















Features of Reversible Motor

① Possible for frequent switch of direction
Starting torque of Reversible Motor is designed to be large for 
     bi-directional operation within short times.
Use built-in brake mechanism to shorten overrun
Suitable for Using frequent switch of direction
⑤ 30 minutes of Rated duty

Induction Motor

Today I introduce the stucture of AC Induction Motor.

It is important to keep the same airgap (360degree) as fixing stator and rotor by housing.
To keep the same airgap, relationship among Stator, Rotor, and Housing should be perpendicular and parallel.










*It is important to perpendicular and parallel for Motor assembly.

Motor Kinds_AC Small Geared Motor

This is a simple explanation about AC Motor Kinds.
















Generally Motor Kinds are distinguished by Motor Structure.

ex) Reversible Motor = Induction Motor + Temporary Brake

What is Motor?

Basically I would like to explain what motor is.

The motor is a driving source of the device when the device you want to do something.

That is, when supplying electricity to the motor the electrical power makes rotating power by the rotor. This rotating power is transited through belts and gears, and direct object to need moving.  

Therefore, the motor is an important thing that can be described as the heart of the machine in any products. 

In short, the motor is a device that changes electrical energy into mechanical energy.

Small Geared Motor Application


Small Geared Motors are used widely wherever needs an electric power.
Above example is one of representative application, and other applicable area is numerous.
