Description

Designed for high-precision industrial motion control, the Mitsubishi Electric HG-KR13B is a low-inertia, small-capacity rotary servo motor engineered for the MELSERVO-J4 series. This 100W motor features an integrated electromagnetic brake, making it suitable for vertical axis applications or systems requiring dynamic position retention. With its integrated absolute/incremental 22-bit high-resolution encoder, the module delivers smooth operation and high-accuracy positioning even at low speeds.

The HG-KR13B is compatible with various SSCNET III/H, CC-Link IE Field, and general-purpose interfaces when paired with the corresponding MR-J4 servo amplifiers. Its robust design provides high reliability in harsh manufacturing environments, utilizing a fully enclosed, self-cooling structure with an IP65 ingress protection rating.

Features

High-Resolution Feedback: Equipped with a 22-bit encoder delivering 4,194,304 pulses per revolution for precise position feedback.
Electromagnetic Brake: Integrated holding brake ensures safe axis retention during power-off states.
Low Inertia Design: Optimized for rapid acceleration and deceleration cycles.
Enclosed Structure: IP65-rated self-cooling enclosure (excluding the shaft throughput) protects against dust and water splash.
Flexible Communication Compatibility: Supports SSCNET III/H, CC-Link IE Field, and analog/pulse train networks via compatible MR-J4 amplifiers.

Applications

Packaging and sealing machinery
Semiconductor manufacturing equipment
Textile processing and weaving systems
Small-scale material handling and multi-axis Cartesian robots
Vertical lift axes requiring holding brakes

Installation Guidelines

Shaft Alignment: Ensure precise mechanical alignment of the motor shaft with the coupling to stay within the allowable radial (88 N) and thrust (59 N) load limits.
Environment: Mount the motor indoors, free from direct sunlight, corrosive or flammable gases, oil mist, and heavy dust accumulation.
Grounding: Ensure proper grounding connection to the servo amplifier's PE terminal to minimize electromagnetic interference (EMI).
Brake Control: The integrated electromagnetic brake is designed solely for holding and must not be used for dynamic braking of the axis.

What is the function of the 'B' suffix in the HG-KR13B part number?

The 'B' suffix denotes that this motor model is equipped with an integrated electromagnetic holding brake, which is critical for holding vertical axes or loads in place when power is removed.

Which servo amplifiers are compatible with the HG-KR13B motor?

The HG-KR13B is compatible with various Mitsubishi MELSERVO-J4 amplifiers, including the MR-J4-10A (general-purpose), MR-J4-10B (SSCNET III/H), and MR-J4-10GF (CC-Link IE Field) series.

Can the electromagnetic brake on the HG-KR13B be used to stop a moving motor?

No, the electromagnetic brake is designed strictly for holding a stationary load (holding brake). Using it to decelerate or stop a spinning motor will cause premature wear or damage to the internal brake components.
