Motor Controllers
Product Overview
Retrofit IoT control module for any existing three-phase motor starter. Adds remote control, scheduling, phase-loss protection, and dry-run protection to 415V AC DOL and Y-Δ starters.
Section: Moto-X 3-Phase
What is the Moto-X 3-Phase?
The HPzenAi Moto-X 3-Phase (MX-3P) is a retrofit IoT control module that brings smart control to any existing three-phase motor starter — DOL contactors, star-delta panels, or MPCB assemblies. It connects to the contactor coil outputs of the existing starter and enables remote start/stop, scheduling, phase-loss protection, dry-run protection, and fault monitoring via the HPzenAi app. Keeps all existing mains, motor, and overload wiring intact.
Highlights
- Retrofits Any 3-Phase Starter: Compatible with DOL, star-delta, and MPCB-based three-phase starters — wires directly to existing contactor coil outputs
- Phase-Loss Detection: Monitors the three-phase supply and triggers an automatic stop and alert if any phase is lost — prevents motor burn-out from single-phasing
- Dry-Run Protection: Integrates with HPzenAi level sensors to stop the motor automatically when the water source runs dry
- Scheduling & Automation: Daily and weekly motor schedules, sensor-triggered start/stop rules, and multi-condition automation via the HPzenAi gateway
