1. Core Concept

• All‑in‑one: Gearmotor + motor starter + protection in one unit.

• Decentralized: Mounted directly on the motor; no cabinet space needed.

• Power range: 0.37 kW … 3 kW.

• Typical use: Conveyors, packaging, logistics, food & beverage.

2. Main Types（MSW series）

MSW‑1E / 1EM（Electronic, 1 direction）

• Contactless electronic star bridge switch.

• One rotation direction（CW/CCW via phase sequence）.

• Control: 24 V DC on/off signal.

• Part example: MSW‑1EM‑B0（24 V DC, 3×400 V）.

MSW‑2S（Contactor, 2 directions）

• With contacts（electromechanical）.

• Reversing starter: CW + CCW（independent of phase sequence）.

• Control: 24 V DC CW/CCW signals.

3. Key Specifications

• Voltage: 3×380–500 V AC ±10%, 50/60 Hz.

• Control: 24 V DC logic; M12 connectors for control & power.

• Protection:

  • Thermal winding monitoring（integrated, auto‑reset）.

  • Overload: 150% / 60 s.

• Enclosure: IP54（standard）; IP55/IP65/IP66 optional.

• Ambient temp: −25 °C … +40 °C（+60 °C derated）.

• Communication: Optional AS‑Interface（integrated or external）.

4. Features

• No cabinet: Reduces wiring, cost, and installation time.

• Compact: Terminal‑box integration; same footprint as standard gearmotor.

• Brake control: Integrated brake management（for SEW brake motors）.

• ATEX: Available for Zone 22（dust）.

5. Part Number Example

• MSW = MOVI‑SWITCH

• 1E = Electronic, 1 direction

• M = 24 V DC control

• B0 = Standard logic

• AVS1 = Gearmotor variant

6. Comparison

• vs. MOVIMOT（MM‑D）: MOVI‑SWITCH is a starter（on/off/reverse）, not a variable‑speed inverter.

• vs. Traditional starters: No cabinet, less wiring, decentralized.
