BLDC Motors

670 models

Electronically commutated, long-life and efficient; speed is roughly proportional to voltage.

Inner Rotor · Outer Rotor · Integrated Driver · Drone & RC Motors

Brushed DC Motors

5 models

Simple construction and low-cost drive; runs directly from a DC supply.

Iron-core · Coreless

Stepper Motors

12 models

Open-loop positioning by pulses, with high torque at low speed.

2-phase Hybrid · 3-phase Hybrid · Closed-loop

Servo Motors

8 models

Permanent-magnet synchronous motors with high-resolution encoders for fast, closed-loop control.

AC Servo – Low Inertia · AC Servo – Medium Inertia · Low-voltage DC Servo

AC Induction Motors

10 models

Rugged and maintenance-free; line-start or speed-controlled by VFD.

3-phase · Single-phase

Gear Motors

6 models

Motor and gearbox combined for higher output torque.

Planetary · Parallel-shaft · Worm · Harmonic

Special Motors

9 models

Direct-drive and linear motion solutions.

Linear · Torque (DD) · Voice Coil

Sizing tools

Power–torque conversion, KV / Kt / Ke, gearbox output, stepper resolution and inertia matching.

Sizing in three steps

  1. 1

    Define the load

    Estimate required torque, speed and duty cycle (continuous / intermittent), with a 1.5–2× margin.

  2. 2

    Choose the type

    Steppers or servos for positioning, BLDC or VFD-driven induction for speed control, brushed DC for simple low-cost drives.

  3. 3

    Check the details

    Verify voltage, current, inertia ratio and mounting, and confirm the operating point on the curves.
