Featured Products
Applications
Washing Machines
- Especially for pulsator washing machines, the drainage motor enables automatic drainage control, consisting of a synchronous motor, transmission system, and an integrated control system.
Dishwashers
- The drainage motor releases wastewater after washing and rinsing, activating the drain valve or pump to ensure complete drainage and maintain efficient, hygienic dishwasher performance.
Floor Cleaning Machines
- The drainage motor controls wastewater discharge by activating valves or pumps, ensuring efficient water removal during or after cleaning for improved hygiene and performance.
FAQ
1. How does a drainage motor work?
It activates a valve or pump through a gear and wire system to release wastewater at specific times during operation.
2. What are a drainage motor's primary parts?
Typically includes a micro synchronous motor, gear system, traction wire, and travel switch.
3. What voltage options are available?
Drainage motors are available in AC (110V/220V) and DC (12V/24V) configurations depending on the appliance.
4. Is the drainage motor waterproof?
Most drainage motors have splash-proof or waterproof enclosures suitable for wet environments.
5. Can I use the same motor for all appliances?
Not necessarily. Motors must match the voltage, torque, and structural requirements of each device.
6. What is the lifetime of a drainage motor?
Generally ranges from 3–10 years depending on usage, quality, and environment.
7. Does the drainage motor need maintenance?
Very little. Ensure the surrounding components (valve, hose) remain clean and free from debris.
8. Which symptoms indicate a malfunctioning drainage motor?
Water not draining, unusual noise, or failure to engage during drainage cycles.
