Description

Optimized for heavy-duty industrial positioning, the Mitsubishi Electric HF-SP202B operates as a high-performance, medium-inertia AC servo motor equipped with an integrated electromagnetic holding brake. Engineered specifically for integration with the MELSERVO-J3 drive platform, this brushless motor delivers stable speed control and exceptional torque-to-inertia performance in demanding dynamic applications. The robust physical construction, featuring high-grade winding insulation and dust/water protection, ensures long-term operational reliability on the factory floor.

Key Features

Medium Inertia Design: Perfectly balanced rotor inertia minimizes mechanical resonance and load mismatching in belt-driven or high-mass systems.
Electromagnetic Holding Brake: Factory-installed 24VDC electromagnetic brake prevents axis drop or drift during power-loss or control-disable states.
High-Resolution Feedback: Designed for seamless interface with absolute/incremental encoder systems to ensure sub-micron position repeatability.
Industrial Enclosure: Sealed connection architecture protects internal windings from standard industrial particulate and moisture ingress.

Applications

CNC Machine Tools: Precise feed axis control for milling, turning, and grinding equipment.
Material Handling Systems: Driving vertical transfer lifts, gantry robots, and automated storage/retrieval systems (ASRS).
Packaging Machinery: Rotary indexers, cartoners, and high-speed packaging feed lines requiring rapid stop-start cycles.
Automotive Assembly: Multi-axis welding positioners and robotic articulation joints.

Empirical Engineering Insights

Alternative Models & Compatibility

The HF-SP202B is natively matched with the 200V class MR-J3-200A and MR-J3-200B servo amplifiers. When transitioning legacy plants from older MR-J2S setups (such as HC-SFS202B motors), users must account for differences in encoder communication protocols and connector pinouts. Upgrading to the MR-J4 series requires a conversion cable or opting for the HG-SR202B motor equivalent, which features updated encoder architecture.

Application Pitfalls & Engineering Notes

A common failure point in vertical-axis installations is using the electromagnetic brake to decelerate or stop a moving load. The brake on the HF-SP202B is designed strictly as a static holding brake; engaging it while the shaft is spinning at 2000 r/min will cause rapid friction wear and catastrophic mechanical brake failure. Ensure your PLC or drive logic decelerates the motor to 0 r/min before dropping the brake control relay.

Commissioning & Wiring Tips

Always install a dedicated surge absorber (diode or varistor) in parallel with the 24VDC brake control relay coil to prevent high-voltage inductive spikes from damaging the amplifier output cards or PLC DO modules. Route encoder cables in separate grounded steel conduits away from high-current motor power cables to minimize electromagnetic interference (EMI) which can cause encoder feedback faults.

Installation Guidelines

CRITICAL WARNING: Prior to commencing installation or maintenance, ensure all primary 3-phase AC power sources to the servo amplifier are completely de-energized. Wait at least 15 minutes to allow internal DC bus capacitors to fully discharge. Verify zero-voltage state on the amplifier terminals with a certified multimeter before handling motor connection cables.

1

Mechanical Alignment: Securely mount the motor to a rigid machine frame. Ensure parallel and angular shaft alignment to the driven load is within 0.03mm to prevent radial load stress on the bearings.

2

Power & Brake Cabling: Connect the U, V, W, and PE terminals to the servo amplifier motor outputs. Route the B1/B2 brake lines directly to the external 24VDC holding circuit.

3

Encoder Feedback Connection: Insert the high-resolution feedback cable plug into the motor encoder connector, ensuring the retaining collar is locked to maintain environmental sealing.

FAQ

Can this motor be operated without a 24VDC power supply connected to the brake?

No. The electromagnetic brake is a fail-safe holding brake. Without a 24VDC supply applied to the brake terminals to release it, the shaft will remain mechanically locked and will prevent rotation.

Which servo amplifier series is recommended to run this motor?

This motor is matched for use with the 200V class MR-J3-200A (Analog/Pulse) or MR-J3-200B (SSCNET III) servo amplifiers.

Does the brake connection require specific polarity?

The electromagnetic holding brake coils are non-polarized. However, the protective flyback diode/surge absorber installed across the control relay coil must be polarized correctly to avoid short circuits.

Can I use this motor in environments with fine metallic dust?

Yes, the motor body features high-grade IP67 environmental protection. However, the shaft-through section is IP65, so a shaft oil seal must be installed if exposed to splashing oil or excessive metallic dust.
