Motor Product Lines
From general-purpose induction machines to high-efficiency permanent magnet, from NEMA frames to hazardous-area protection — 30+ series and 3,000+ ratings covering the mainstream industrial duty envelope.
No series matches every filter at once. Clear one of them, ortell us the duty and we will size it — custom builds cover ratings the standard series do not.
AC Induction
General-purpose IEC-frame induction motors across IE3, IE4 and IE5, plus the large-power and variable-frequency variants of the same platform.
High Voltage
Cage-rotor high-voltage machines at 3.3 kV, 6 kV and 10 kV for mill, fan, compressor and hoist duty.
NEMA Standard
Built to the NEMA standard at 60 Hz for the North American market — T-frames, NEMA voltages, CSA and US efficiency certification.
Hazardous Area
Flameproof "d" machines for explosive gas atmospheres and enclosure "t" machines for combustible dust, in fixed-speed and variable-frequency versions.
Permanent Magnet
Permanent magnet synchronous machines from line-start general purpose through high-speed direct drive and low-speed gearless drive systems.
Special Purpose
Pole-changing multi-speed, dual-power, high-starting-torque and electromagnetic brake machines for duty the standard series does not cover.
Control Systems
Matched drives and control cabinets, supplied with the motor as one drive system.
Custom Motors
Beyond the standard series, LEADGO builds to specification across the full voltage range from low voltage up to 10 kV. Voltage, windings, mechanical construction and mounting can all be adapted — from a small change to a standard model through to designing a complete system from scratch. Three depths of customisation are offered.
Standard Customisation
Changes applied to an existing standard series: voltage, frequency, shaft extension dimensions, foot and flange mounting dimensions, ingress protection, insulation class and enclosure construction. Smallest change, shortest lead time.
Drawing-Based Customisation
The customer supplies drawings and LEADGO manufactures to them — special winding configurations, special rotor construction and other components. Suited to applications with defined engineering specifications that must match an existing system exactly.
System Customisation
A motor designed from scratch for the customer's specific installation, delivered as a complete motor system solution. For applications the standard product lines cannot cover at all.
What is a permanent magnet synchronous motor?
A permanent magnet synchronous motor (PMSM) replaces the squirrel-cage rotor of a conventional induction machine with permanent magnets. No magnetising current is required, so efficiency stays high at low speed and light load — which is exactly what matters on cyclic duty such as mine crushers and oilfield beam pumps. The central trade-off at selection is capital cost against lifetime energy saving; the energy comparison calculator works that through.
Permanent magnet machines are graded under GB 30253, which is a different scale from the IE classes of IEC 60034-30-1 — that one covers line-fed induction motors. The grades do not convert between the two, which is why the efficiency filter above returns induction series only. A permanent magnet motor can still be given an IE code, but under GB/T 32891.2—2019 (identical to IEC TS 60034-30-2), the separate classification for variable-speed AC machines. If your specification needs an IE code on a permanent magnet motor, ask us and we will quote it against that standard.
