This granite cutting video presents a Huada diamond wire saw with permanent magnet drive technology. The archived notes focus on pulling torque, voltage variation and electrical demand rather than on a named quarry or measured granite cut.
Granite is the stated application
The title narrows this recording to granite, although the source also describes the machine family for different quarry stones. A granite proposal still needs the actual material, bench geometry, wire construction and water conditions. The video does not establish one universal setting for every hard stone.
Permanent magnet drive claim
The motor is described as maintaining torque throughout the frequency range and providing strong pulling torque at low frequency for easier starting. The source also states efficiency up to 30% above standard machines. No baseline model, cut area or electrical record is supplied, so the percentage remains a manufacturer comparison.
Check power capacity with measurements
Wide voltage suitability and lower consumption are linked with operating more wire saws without rebuilding the quarry power system. That decision requires measured voltage, transformer capacity, cable length and simultaneous load.
For a comparable granite trial, use the same stone, wire, cutting plane and water for both machines. Record area, time and amperage. Those data provide a fair way to assess the drive while keeping the edited recording separate from a site acceptance result.
