MELSERVO-J4 Rotating Type Servo Motor HG-KR Series (200 V Class, Small Capacity, Low Inertia)
- On Sale Till 30/06/2026
The maximum rotation speed is 6,000 r/min against the rated rotation speed of 3,000 r/min.
The maximum torque is applicable with 350% of the rated torque, and high torque is realized in the high rotation range.
[Features]
・ High resolution absolute position encoder (4,194,304 pulses/rev (22 bit)) is standard equipment. It achieves higher accuracy positioning.
・ IP65 is adopted as standard. No problem with water and dust
・ The power cable, encoder cable, and electromagnetic brake cable can be pulled out from the servo motor either on the load side or the non-load side by selecting the cable.
・ Torque ripple is greatly reduced by optimizing the combination of motor poles and slots.
・ It operates smoothly even at low speed operation, which is easily affected by torque ripple, and improves stability.

2. If the load to motor inertia ratio exceeds the indicated value, contact your local sales office.
3. The value on the gear reducer input axis.
4. Except for the shaft-through portion. IP classifies the degrees of protection provided against the intrusion of solid objects and
water in electrical enclosures.
5. In the environment where the servo motor is exposed to oil mist, oil, or water, the servo motor of the standard specifications may
not be usable. Please contact your local sales office.
6. The servo motor alone. The following figure shows the vibration directions. The value is the one at the part that indicates the
maximum value (normally the opposite to load-side bracket). When the servo motor stops, fretting is likely to occur at the
bearing. Therefore, suppress the vibration to about half of the permissible value. Note that this does not apply to the geared
servo motor.
7. V10 indicates that the amplitude of a servo motor alone is 10 μm or less. The following figure shows the servo motor mounting
position for measurement and the measuring position.
8. The servo motor alone.
POINT
▪ For the system where the unbalanced torque occurs, such as a vertical axis,
the unbalanced torque of the machine should be kept at 70% or lower of the
motor's rated torque.
The torque characteristics shown in the following diagrams are for the servo motor alone. When the input
power supply specification of the servo amplifier is 1-phase 230 V AC, the torque characteristic is indicated
by the heavy line. For 1-phase AC 100 V, part of the torque characteristics is indicated by a broken line,
and for 1-phase 200 V AC part of the torque characteristics is indicated by a continuous line.
