Moteur servo Mitsubishi HG-KR43B

Description

Designed for high-precision industrial motion control, the HG-KR43B low-inertia rotary servo motor operates within the Mitsubishi Electric MELSERVO-J4 series ecosystem. This motor is engineered for application profiles requiring fast acceleration, rapid deceleration, and high-frequency positioning cycles. Operating on a 200V class power supply, the unit delivers stable torque output and is optimized for modern automated manufacturing lines.

The feedback loop is driven by an integrated high-resolution 22-bit encoder, enabling exceptional positioning accuracy of over four million pulses per revolution. To accommodate diverse control schemes, this motor is fully compatible with multiple servo amplifier variations, supporting CC-Link IE Field network interfaces, SSCNET/H motion networks, and standard general-purpose pulse/analog interfaces.

Features

• Low-inertia rotor construction optimized for high-duty dynamic cycles.
• Built-in 22-bit absolute/incremental encoder offering 4,194,304 pulses per revolution.
• Dust and liquid splash protection rated at IP65 (excluding shaft-through portion).
• Thermal class 130 (B) insulation rating for reliable heat dissipation.
• Compact footprint with an integrated electromagnetic brake for fail-safe shaft holding.

Applications

• High-speed packaging and filling systems
• Semiconductor and electronics assembly machines
• Material handling and robotic pick-and-place systems
• Multi-axis X-Y positioning tables
• Textile processing machinery

Installation Guidelines

• Shaft Handling: Avoid direct impacts or heavy radial shocks to the shaft during coupling installation to prevent damage to the high-resolution encoder optical disc.
• Alignment: Ensure strict concentricity between the motor shaft and the driven machinery. Misalignment exceeding specifications will shorten bearing life.
• Environmental Protection: Mount the motor indoors, free from direct exposure to corrosive gases, oil mist, or conductive dust. Ensure the cable entry points are correctly sealed to maintain the IP65 rating.
• Mounting Position: The motor can be mounted horizontally, vertically shaft-up, or vertically shaft-down. If mounted vertically shaft-down, take appropriate measures to prevent oil or water from pooling at the shaft seal.
