Product Overview: Panasonic MHMJ042G1U Servo Motor
The MHMJ042G1U is a flagship AC brushless servo motor from the advanced MINAS A6 Series by Panasonic Industry. This 400W model is a Low Inertia type, specifically designed for high-dynamic applications that require instant response and rapid direction changes. It is the premier choice for pick-and-place robotics, electronic component assembly, and high-speed labeling systems where sub-millimetric precision and high throughput are the primary requirements.
High-Dynamic Performance and 23-bit Resolution
The MHMJ042G1U features an industry-leading 23-bit absolute/incremental encoder, providing 8,388,608 pulses per revolution. This ultra-high resolution ensures exceptional path-following accuracy and ultra-smooth rotation, even at very low speeds. The low-inertia rotor design allows for a massive acceleration constant, enabling the motor to reach its rated speed of 3000 RPM almost instantaneously. Its compact 60mm frame size delivers an incredible power-to-weight ratio, optimizing the efficiency of moving axes.
