How to Specify a Motor Assembly
Specify a motor assembly by output torque and speed, supply voltage, the motor technology that suits the duty (stepper, BLDC or servo), feedback, gearing, environment and annual volume. Delta Line can then combine motor, gearbox, encoder and drive into a single tested unit.
Stepper, BLDC or servo?
| Technology | Good for |
|---|---|
| Stepper | Low-cost positioning at modest speeds; simple control |
| Brushless DC | Efficient continuous duty, long life, speed control |
| Servo | High dynamics and torque density; closed-loop performance |
| Integrated motor | Saving space and wiring with built-in control |
What to send EAC
- Output torque and speedAt the shaft after any gearbox.
- Supply voltageDC bus or AC line.
- Positioning needsOpen or closed loop; encoder resolution.
- Gearing and outputRatio, in-line or right-angle, shaft style.
- EnvironmentIP rating, temperature, noise.
- EnvelopeSpace and mounting.
- Annual volumeCustom assemblies make most sense at production quantities.
