Original Mitsubishi HG series Servo Motor 100W HG-SN102J-S100

Short Description:

AC servo motor: servo system is generally composed of servo amplifier and servo motor.

The rotor inside the servo motor is a permanent magnet. The U / V / W three-phase electricity controlled by the servo amplifier forms an electromagnetic field. The rotor rotates under the action of the magnetic field. At the same time, the encoder of the motor feeds back the signal to the driver. The driver adjusts the rotation angle of the rotor according to the comparison between the feedback value and the target value. The accuracy of servo motor depends on the resolution of encoder.

AC servo system classification:  mr-j, mr-h, mr-c series; Mr-j2 series; Mr-j2s series; Mr-e series; MR-J3 series; Mr-es series.

About Mitusbishi AC Servo Motor:Stator:
First have a look at the figure shown below, representing stator of ac servomotor:stator of ac servomotorThe stator of ac servo motor consists of two separate windings uniformly distributed and separated at 90°, in space. Out of the two windings, one is referred as main or fixed winding while the other one is called control winding.
A constant ac signal as input is provided to the main winding of the stator. However, as the name suggests, the control winding is provided with the variable control voltage. This variable control voltage is obtained from the servo amplifier.It is to be noted here that to have a rotating magnetic field, the voltage applied to the control winding must be 90° out of phase w.r.t the input ac voltage.

Rotor: The rotor is generally of two types; one is squirrel cage type while the other is drag cup type.
The squirrel cage type of rotor is shown below:squirrel cage rotorIn this type of rotor, the length is large while the diameter is small and is constructed with aluminium conductors thus weighs less.It is to be noted here that the torque-speed characteristics of a normal induction motor have both positive as well as negative slope regions that represent unstable and stable regions, respectively.

However, ac servo motors are designed to possess high stability thus, its torque-slip characteristics must not have a positive slip region. Along with this the torque developed in the motor must reduce in a linear manner with speed.
To achieve this the rotor circuit resistance should have a high value, with low inertia. Due to this reason, while constructing the rotor, the diameter to length ratio is kept smaller.The reduced air gaps between the aluminium bars in the squirrel cage motor facilitate a reduction in magnetizing current
