Servo/Motion – Servomotors

Highest Functionality


Utilising the most advanced concentrated winding techniques and latest technology, these brushless servo motors are among the most compact on the market.

Mitsubishi Servo Motors are made to high standards and offer a wide range of power, speed and inertia ratings providing a motor for all applications. Ranging from 50W through to 55kW and with specialist type motors available (flat "pancake"motors) the new Super Series Servo Motors complete the line-up of products offered by Mitsubishi Electric.

Also, all motors in the Mitsubishi Super Series are fitted with absolute encoders as standard.Therefore, an absolute system can be created by simply providing power to Servo amplifier via a battery. Once this has been done the backup battery allows the Servo motor position to be constantly monitored, even when disconnected from the power.



Digital AC Servo Motor and Driver

High performance and function for systems where precision, smart control, safety, and easy configuration are needed.


Key Features

20 bits/revolution, 1.04 million pulses
Ensures smoother operation and reduced vibration while maintaining position as well as accurate positioning within a short setting time.

Manual/Auto Notch and Damping Filters
These filters will automatically detect vibration and provide simple auto-setting. These filters greatly reduce noise and vibration.

Low cogging torque
We have achieved the industry's lowest cogging* by utilizing a new 10-pole rotor design and a magnetic field parsing technique. Positioning and stability are greatly improved with the result of minimal torque variation. This results in improved speed stability and positioning

2.0 kHz frequency response
Achieves the industry’s fastest frequency response of 2.0 kHz*. This allows a highly advanced system to be created that achieves the industry’s fastest speed and positioning response.

Highly Functional Real-time Auto-Gain Tuning
Incorporates the industry's quickest high-performance real-time auto-gain tuning featuring simple setup. After installation, tuning will be completed automatically after few operations.

IP67 enclosure rating for increased environmental resistance.
Our improved motor seals and direct-mount connectors in the motor power supply and encoder input-output areas contribute to this unit's IP67 enclosure rating

Advanced Functionality!
Reduce Mechanical Vibration
Quick suppression of vibration with an adaptive filter.

Even if the resonant frequency changes, realtime evaluation automatically follows the changes to reduce the effect of vibration due to low mechanical rigidity, such as for conveyer belts.

Reduce Tact Time
Reduce mechanical vibration with the vibration control function.

By removing the vibration frequency components between the stop position and the intermediate position, vibration that occurs due to low mechanical rigidity can be suppressed.

Other Features

High-speed Response

The G-series AC Servo Motors and Servo Drivers have achieved high-speed response capabilities exceeding OMRON’s W-series models, with a high-response frequency of 1 kHz (compared to 400 Hz for the W Series).

Suppressing Vibration of Low-rigidity Mechanisms during Acceleration / Deceleration

The damping control function suppresses vibration of low-rigidity mechanisms or devices whose ends tend to vibrate. Two damping filters are provided to enable switching the vibration frequency automatically according to the direction of rotation and also via an external signal. In addition, the settings can be made easily merely by setting the vibration frequency and filter values, and you are assured of stable operation even if the settings are inappropriate.

High-speed Positioning via Resonance Suppression Control

The real-time auto-tuning function automatically estimates the load inertia of the machine in real-time and sets the optimal gain. The adaptive filter automatically suppresses vibration caused by resonance. Also, two independent notch filters make it possible to reduce vibration of a mechanism with multiple resonance frequencies.
