MELSERVO-J4 Series Rotary Servo Motor
Equipped with High-Resolution Absolute Position Encoder
Servo motors are equipped with a high-resolution absolute position encoder of 4,194,304 pulses/rev (22-bit) as standard. Positioning accuracy is increased.
- * 262,144 pulses/rev (18-bit) for HG-AK series.
Improved Environmental Resistance
Ingress protection*2 of servo motors: HG-KR/HG-MR/HG-RR/HG-UR: IP65
HG-SR/HG-JR: IP67*1
HG-AK: IP55
- *1. HG-JR 1000 r/min series 15 kW or larger, HG-JR 1500 r/min series 22 kW or larger, and HG-JR 2000 r/min series are rated IP44.
- *2. The shaft-through portion is excluded.
Cable Leading Direction
Cables for power, encoder, and electromagnetic brake are capable of being connected either in direction or in opposite direction of the load side, depending on the cable selection. (HG-KR and HG-MR series)
Reduced Torque Ripple during Conduction
■Torque ripple
The torque ripple is reduced owing to the optimized combination of the numbers of the motor poles and the slots. Thereby, smooth rotation is achieved even during a low-speed operation which is more likely affected by the torque ripple, improving the operation stability.
