There are two driving forms: inverter permanent magnet synchronous motor drive and inverter permanent magnei
roller drive.Both kinds of direct drive can meet the explosion-proof requirements for mine use. Their respective characteristicsare as follows:
Variable frequency permanent magnet synchronous motor drives the belt conveyor
(1) After the inverter permanent magnet synchronous motor is used in the whole machine, low-speed direct driveis realized;Without reduction gearbox, it simplifies the transmission chain and improves the reliability of the whole ma-chine.
(2) The whole machine adopts variable frequency drive system, full vector control and diversified operation modes
(3) The whole machine can realize low speed and larae toraue starting, smooth starting, and overload starting.
(4) The whole machine can realize intelligent control, and power balance can be realized when multiple machinesare running.
(5) Permanent magnet direct drive has small volume, high eficiency, simple installation and low maintenance cost.
(6) Permanent magnet roller adopts four-guadrant control, which can be used for system braking.
Variable frequency permanent magnet roller drive type belt conveyor
(1) The whole machine adopts permanent magnet roller to realize low- speed direct drive;No reduction box or reduc-tion box built - in, simplify the transmission chain, improve the reliability of the whole machine.
(2) The whole machine adopts variable frequency drive system, full vector control and diversified operation modes.
(3) The whole machine can realize low speed and large torgue starting, smooth starting, and overload starting.
(4) The whole machine can realize inteligent control, and power balance can be realized when multiple machines are-running.
(5) Permanent magnet direct drive has small volume, high eficiency, simple installation and low maintenance cost.
(6) Permanent magnet roller adopts four-quadrant control, which can be used for system braking.
(7) The roller and motor are integrated in structure, which reduces the installation space, especially suitable for under-ground coal mine trough and places with limited installation space
