3.3 વિદ્યુત જોડાણ
The motor operates on 208-230V and includes 36-inch leads for connection. It is a Permanent Split Capacitor (PSC) motor and requires an external capacitor (5 MFD capacitor included).
વાયરિંગ સૂચનાઓ:
- Ensure the power supply is disconnected at the circuit breaker before making any electrical connections.
- Connect the motor leads to the appropriate power supply terminals according to the wiring diagram provided on the motor's nameplate or in the technical drawing.
- The motor has reversible rotation. Refer to the wiring diagram for instructions on how to reverse rotation if necessary.
- Connect the included 5 MFD capacitor as per the wiring diagram.
- All connections must be secure and insulated to prevent short circuits and ensure safety.
Refer to the technical drawing for detailed wiring information:

4. ઓપરેટિંગ સૂચનાઓ
Once properly installed and wired, the Nidec 5441H motor is ready for operation.
4.1 પ્રારંભિક સ્ટાર્ટ-અપ
- Before applying power, double-check all electrical connections and ensure the motor is securely mounted.
- સર્કિટમાં પાવર પુનઃસ્થાપિત કરો.
- Initiate motor operation through the connected control system.
- Observe the motor during its first few minutes of operation for any unusual noises, vibrations, or overheating.
4.2 સામાન્ય કામગીરી
The motor is designed for continuous duty in a Totally Enclosed Air Over (TEAO) enclosure, suitable for ambient temperatures up to 70°C. It operates at 1075 RPM.
The motor's rotation is reversible. If the application requires a different rotation direction than the initial setup, refer to the wiring diagram in Section 3.3 for instructions on how to change the rotation.

5. જાળવણી
The Nidec 5441H motor is designed for low maintenance. However, periodic checks can help ensure optimal performance and extend its lifespan.
WARNING: Disconnect all power before performing any maintenance.
5.1 નિયમિત નિરીક્ષણ
- વિઝ્યુઅલ તપાસ: Periodically inspect the motor for any signs of physical damage, corrosion, or loose connections.
- સ્વચ્છતા: Ensure the motor's exterior is free from excessive dust, dirt, or debris, which can impede cooling. The Totally Enclosed Air Over (TEAO) enclosure helps protect internal components, but external cleanliness is still important.
- કંપન: Check for excessive vibration during operation, which could indicate misalignment or bearing issues.
- ઘોંઘાટ: Listen for unusual noises that might suggest internal problems.
5.2 બેરિંગ્સ
This motor is equipped with ball bearings, which are typically sealed and lubricated for life, requiring no routine lubrication. If unusual bearing noise is detected, consult a qualified technician.
5.3 Capacitor Check
The 5 MFD capacitor is a critical component. If the motor struggles to start or runs inefficiently, the capacitor may need to be tested or replaced by a qualified technician.
