This page pairs a permanent magnet wire-saw feature note with the same saved video URL used by the horizontal-cutting article. It should therefore be read as technical context for the drive, not as a second independent performance recording.
Torque and voltage claims
The source describes constant torque throughout the frequency range and strong pulling torque at low frequency for easier starting. It also says the machine is suitable where voltage varies. No motor rating, voltage range, stone or quarry electrical data are supplied.
Efficiency statement needs a baseline
Efficiency up to 30% above standard machines is stated, together with the possibility of operating more wire saws without rebuilding the power system. The reference machine and comparison conditions are absent. Transformer capacity and simultaneous load still require an electrical calculation.
Avoid duplicate evidence
Because the horizontal-cutting article and this page use the same recording, camera content cannot support two separate trials. This article retains its existing URL and title but limits itself to the archived permanent magnet claims.
A genuine performance case needs a named machine, stone, wire, cut area, time and amperage beside the baseline. Until then, the 30% figure remains a manufacturer comparison rather than a measured result from this video.
