Product Characteristics
Star-Delta Switchable Dual-Voltage Stator Windings
The stator coils adopt switchable star/delta wiring design with conversion links inside terminal box. It fits two mainstream industrial three-phase voltages 380V and 400V without winding modification, compatible with domestic and overseas power grids for global sales.
Modular Frame with Integrated Aluminum / Separated Cast Iron Structure
Low-power models adopt one-piece die-cast aluminum housing while heavy-duty versions use thick gray cast iron frame. Standard pre-reserved grease nipples, temperature measuring holes and mounting positions enable separate disassembly of end covers and bearing units, simplifying maintenance without full motor removal.
Low-Loss Optimized Silicon Steel Laminated Core
Stator and rotor cores are stacked with high-permeability low-loss cold-rolled silicon steel sheets with insulated passivated edges, cutting core loss under no-load operation, reducing eddy current heat generation and controlling overall temperature rise fundamentally.
Product advantages
High Starting Torque & Energy Efficiency
Balanced three-phase magnetic field provides stable and sufficient starting torque for smooth heavy-load startup without stalling. It achieves higher efficiency than single-phase motors of identical frame size, minimizing power loss during continuous full-load operation and cutting long-term electricity expenses.
Flexible Multi-Mounting Options for Various Equipment
One single frame supports three mainstream mounting types: B3 horizontal foot-mounted, B5 vertical flange-mounted and B35 combined horizontal & vertical. Users can switch installation forms by replacing end cover parts, cutting stock model varieties and inventory costs.
Low Noise & Eco-Friendly High Efficiency Standard
Precisely dynamically balanced rotor matched with inclined silent cooling fan blades keeps noise below industrial average limits. High-permeability iron core boosts motor efficiency, multiple models reach IE3 premium efficiency grade, saving power consumption and meeting global energy-saving access standards.

FAQ
Q: Can this IP55 3-phase motor work long-term in semi-open factory yards?
A: It resists low-pressure multi-angle water spray and dust accumulation. A rain and sun shield is recommended for permanent outdoor placement to prevent water seepage from prolonged rain flushing on shaft seals.
Q: What's the maximum allowable long-term operating temperature of Class F windings, and what advantages does it have over Class E insulation?
A: Class F insulation withstands continuous 155°C, while Class E only bears 120°C. It avoids insulation breakdown in hot workshops or enclosed equipment cabins and offers stronger short-time overload resistance.
Q: What inspections must be carried out before restarting the motor stored for over 6 months?
A: Measure winding insulation resistance to ground first, clean aged grease inside bearing housing and refill new lubricant, rotate shaft manually to check jamming, then run no-load for 30 mins to monitor temperature rise and abnormal noise.
