The LG BMG110NHMV is a variable‑speed BLDC inverter compressor for R600a refrigerators and freezers, working on 220–240 V, 50/60 Hz in low‑back‑pressure applications. With a nominal rating close to 1/4 hp and a speed range from 1200 to 4500 rpm, it delivers flexible capacity and high efficiency for modern domestic appliances.
BMG110NHMV technical profile
LG’s catalog lists the BMG110NHMV in the BMG inverter R600a series, designed for high‑efficiency household refrigerators. The nameplate confirms R600a refrigerant, thermal protection and 220–240 V supply.
Main data and operating point
At lower speeds like 1500–1800 rpm, capacity drops to around 102–125 W while COP remains near 1.74–1.75, allowing the compressor to modulate for part‑load efficiency.
Capacity table across speeds
The inverter control lets the same compressor cover a wide load range without cycling, which is reflected in LG’s performance table.
Cooling capacity vs power – BMG110NHMV (R600a LBP)
These values show how the inverter platform lets manufacturers tune energy labels by operating much of the time at lower speeds, while still having 262 W on tap for rapid pull‑down.
Comparison with other LG inverter R600a models
LG’s catalog groups the BMG110NHMV with BMG110NAMV and BMG089 series models, all R600a BLDC compressors for LBP applications. Comparing their data helps installers and designers choose the right size.
LG R600a BLDC inverter comparison
*Cabinet volume estimates are typical ranges inferred from inverter R600a design practice, not explicit catalog values.
The BMG110NHMV thus occupies a sweet spot between the smaller BMG089 series and larger BMK/BMA models, ideal for mid‑size no‑frost or multi‑door refrigerators where load fluctuates strongly.
Comparison with fixed‑speed R600a compressors
To highlight the benefit of inverter technology, it is useful to compare BMG110NHMV with a typical constant‑speed R600a compressor of similar hp rating. LG’s own reciprocating catalog and third‑party suppliers show 1/4 hp fixed‑speed R600a models with similar cooling capacity but higher average power consumption.

This comparison explains why OEMs increasingly specify BMG‑series compressors in premium, energy‑efficient refrigerators.
Safety and application notes for R600a systems
Because BMG110NHMV uses R600a, a flammable hydrocarbon, system design and service procedures must follow IEC and manufacturer guidelines.
- Charge quantities in household refrigerators are limited, typically below 150 g, to remain within safety limits.
- Electrical components near the compressor must be sealed or spark‑free, and any repair involving brazing requires full refrigerant recovery and ventilation.
These constraints do not reduce performance; they simply require disciplined handling, especially when replacing the compressor or modifying pipework.
