01
Magnetic drive
Opposite poles attract, like poles repel. The field turns the rotor and the integrally formed impeller together — no mechanical brush contact.
Inside the motor
A rotating field, not a commutator.
Segmented windings become a ring stator, then a BMC shell. The rotor follows the field. There is no brush to arc, wear, or contaminate the cabinet.
02
Magnetic isolation
A thin isolation sleeve separates stator and rotor. Coils sit in epoxy; rotor and impeller are molded as one. The motor side is specified leak-free to IP68.
03
BMC overmolding
Bulk Molding Compound encapsulates the stator core and windings as a single thermoset structure — rigidity, insulation, heat path and dampening in one shot.
From segment to ring to shell
Coils are wound as segments, positioned and welded into a ring, optically inspected, then overmolded in BMC. The rotor is a permanent-magnet stack that follows the field. Because PEILI winds, forms and overmolds in the same plant, the motor is a controlled BOM rather than a bought-in can.
Driver
The driver is on the drawing, not in a carton of adapters.
A rotating-field board takes mains or a DC bus, feeds the motor, and can hand 24/36 V to neighbouring loads. Speed is an external command when you specify Model 3.
Three kits
Model 1
DC bus input
- Input
- DC 24 V / 36 V
- Output
- Driver board → brushless pump
For systems that already have a 24 V / 36 V DC rail.
Model 2
AC direct, no adapter
- Input
- AC 115 V / 230 V
- Output
- Driver DC output 36 V / 24 V + pump
Mains in. Auxiliary 24/36 V for other components. No external adapter.
Model 3
AC with speed control
- Input
- AC 115 V / 230 V
- Output
- Driver DC output 24 V + adjustable-speed pump
External control signal sets motor speed, flow and pressure.
