Delta Inverter

Delta inverters control motor speed in Guangu Tech polishing machines. They change the fixed power supply (380V, 50Hz) into a variable output. This lets you speed up or slow down the motor. Slower speeds give a gentler polish. Faster speeds give stronger cutting action. Pair with braking resistors for safe motor operation.

Four power ratings are available: 2.2 KW (for GG8520), 3.7 KW (for standard single-motor machines), 5.5 KW (for GG1380 and GG2380), and 7.5 KW (for the largest models). Each inverter comes pre-set for polishing machine use. Just plug it in and go.

Delta is a trusted global brand in motor drives. These inverters are known for being reliable, energy-efficient, and long-lasting. Built-in safety features protect against over-current, over-voltage, under-voltage, and overheating.

You may need a replacement after years of use, a power surge, or when upgrading your machine. Always confirm the correct power rating for your model before ordering. The wrong inverter can damage your motor or give poor results.
