An eight-station stator press & insertion machine is a specialized automation system designed for mass production of stators (the stationary magnetic core component in motors and generators). It integrates pressing, forming, and insertion operations in a multi-station rotary or indexing configuration. Each “station” refers to a fixed position on the machine where a part of the process (such as insertion, pressing, inspection, or transfer) is carried out.
In practice, a stator’s coil, insulation, inner structures, or components are pressed, inserted, or assembled in a sequential, highly automated workflow. With eight stations, the machine can handle eight work steps (or stages) in one rotation cycle, improving throughput while maintaining precision and consistency.
An eight-station stator insertion machine generally consists of:
Indexing rotary table — moves the stator assemblies from one station to the next with high positional accuracy.
Press units — hydraulic, pneumatic, or servo-driven presses at certain stations to insert or press parts into the stator core.
Insertion modules — automated arms, grippers, or feeders that insert small components (e.g. coil limbs, insulation, wedges).
Clamping fixtures / tooling — to hold the stator securely and precisely during press or insertion operations.
Sensors and inspection units — to detect misalignment, bad insertion, or part defects at various stations.
Control system (PLC / motion controller) — to sequence the stations, coordinate motion, timing, pressures, and error handling.
Material feeders / supply units — to feed parts (e.g. insulation sheets, coil parts) to insertion modules.
Safety and guard systems — covers, interlocks, emergency stops to ensure operator safety.
Working Principle (simplified):
A raw stator blank (e.g. with windings already inserted or partially assembled) is loaded into the first station.
The indexer advances the part to each subsequent station.
At different stations, pressing or insertion modules perform tasks (e.g. pressing insulation, inserting wedges, securing end caps).
After the final station, the finished stator assembly is discharged, and the next blank enters.
Throughout the cycle, sensors and checks ensure each insertion or press meets tolerances.
Because all eight stations operate in a pipeline, the machine’s effective throughput per unit time is high.
Choosing an eight-station stator press & insertion machine offers several benefits for motor / generator manufacturers:
High throughput / efficiency – multiple steps happen in parallel, reducing per-unit cycle time.
Consistency and precision – using fixed tooling and coordinated control ensures repeatability and tight tolerances.
Reduced manual labor – automation reduces dependency on skilled operators and lowers error rates.
Compact footprint – compared to separate standalone machines, the integrated system often uses space more efficiently.
Scalability – the modular station design allows you to upgrade or reconfigure some stations for new stator types.
Quality assurance – embedded sensors and inspections catch defects earlier, reducing rework or scrap.
Such machines are widely used in:
Electric motor manufacturing (automotive, home appliances, HVAC).
Generator and alternator production for power plants or renewable energy equipment.
Automotive EV / hybrid motor assembly lines, where high volumes and precision are essential.
Industrial machinery motors (pumps, compressors) where consistent stator quality is critical.
These industries demand high yield, low variation, and scalable production — making multi-station insertion machines a core automation investment.
When selecting or designing an eight-station stator press & insertion system, a few key factors must be weighed:
| Factor | Consideration |
|---|---|
| Stator design variety | Will the stators vary in diameter, slot count, or core thickness? The machine must be flexible or easily retooled. |
| Cycle time & throughput target | Calculate the required cycle per minute to meet production goals and ensure the eight stations are well balanced (no bottlenecks). |
| Press force and accuracy | Some insertions need precise force control (servo or proportional control preferred). |
| Tooling costs | Fixtures, inserts, and changeover tooling must be designed for durability, precision, and maintainability. |
| Control system sophistication | A strong PLC / motion control + diagnostics for fault detection, predictive maintenance, and integration with factory systems. |
| Maintenance & serviceability | Easy access, modular parts, and strong supplier support are essential to minimize downtime. |
