ETEL MWD100‑0128‑00B Linear Motor

The ETEL MWD100‑0128‑00B is a high‑performance ironless linear motor designed for applications that demand absolutely smooth motion with zero cogging. Its ironless design eliminates magnetic attraction between the coil and magnet track, resulting in minimal friction and virtually ripple‑free force output. With a coil length of 128 mm and a width of 100 mm, this motor delivers outstanding force density while maintaining a low moving mass, ideal for high‑speed and high‑acceleration systems.

Core Advantages

• Zero Cogging: No iron core means no cogging force, enabling nanometer‑level positioning accuracy.

• High Force Output: Delivers up to 150 N continuous force (peak 300 N) with forced‑air cooling.

• Low Moving Mass: Lightweight coil assembly allows rapid acceleration and deceleration.

• Excellent Heat Dissipation: Advanced thermal design ensures stable performance even under prolonged high‑current operation.

• Flexible Integration: Compatible with ETEL's DSB2 and AccurET servo amplifiers.
