- Rated Speed: 2000 r/min (Max 3000 r/min)
- Inertia: Medium Inertia
- Rated Torque: 4.8 N·m (Max 14.3 N·m)
- Encoder: 22-bit Absolute
- IP Rating: IP67 (Superior protection)
Technical Superiority: Torque Stability for Heavy Loads
Secure now the HG-SR102 to handle your most demanding industrial tasks. This motor is technically superior for applications with high inertia ratios because the medium-inertia rotor provides a mechanical dampening effect, reducing the risk of oscillation and resonance. The HG-SR102 delivers a massive 14.3 N·m of peak torque, allowing it to move heavy mechanical assemblies with precision. It features an IP67 environmental rating, making it suitable for harsh environments where coolant or water spray is present. When you order the HG-SR102, you are acquiring a motor with a 22-bit high-resolution encoder that enables micro-stepping levels of accuracy, even at the 2000 r/min rated speed. Its internal design includes reinforced insulation and high-performance permanent magnets, ensuring that the motor maintains its torque characteristics over a wide temperature range.
Expert Tips: Thermal Management and Drive Pairing
Because the HG-SR102 is a 1kW motor, it can generate significant heat during continuous heavy-load operations. Ensure the mounting surface acts as a proper heat sink. We recommend pairing this motor with the MR-J4-100A or MR-J4-100B amplifier for optimal current control. Sourcing your HG-SR102 from Atlantechdrives ensures you get a unit with a verified IP67 seal, crucial for longevity in wash-down or machining environments. If using a brake version, ensure the 24V DC brake power is independent of the control power to prevent voltage drops during activation.
Maintenance and Bearing Reliability
Maintenance for the HG-SR102 involves monitoring for grease leakage from the bearings and checking the electrical terminal block for tightness. The high-resolution encoder is sensitive to mechanical shock; always use a puller tool for removing couplings or pulleys to avoid axial shock to the shaft. Sourcing from Atlantechdrives guarantees the hardware reliability and deterministic performance required for 24/7 industrial uptime.
FAQs
Q: What is the benefit of Medium Inertia in the HG-SR102?
A: Medium inertia provides better control stability for loads that are not perfectly balanced or have varying weights, such as a roll of paper or steel.
Q: Does it include a shaft keyway?
A: The standard HG-SR102 often comes with a keyed shaft, but please check the specific suffix (like HG-SR102K) for verification.
