Product Overview
Figure 1: Packard 1/23 Hp 1500 RPM 115 Volt Motor, Model 90420. This image shows the black motor unit with its shaft extending from the front, ventilation slots visible on the casing, and electrical wires with a connector extending from the rear. Mounting bolts are visible around the shaft.
The Packard Model 90420 is a 1/23 horsepower, 1500 RPM, 115 Volt shaded pole motor. It features permanently lubricated sealed sleeve bearings and an open enclosure. It includes automatic overload protection and operates at 60 Hertz. This motor is designed with CWSE (Clockwise Shaft End) rotation and a thru-bolt mounting option.
Setup and Installation
Pre-Installation Checklist:
- Verify that the motor specifications (voltage, RPM, HP) match your application requirements.
- Ensure the mounting surface is stable and capable of supporting the motor's weight (approximately 4.75 lbs).
- Gather necessary tools: wrenches, screwdrivers, wire strippers, electrical tape/connectors.
Installation Steps:
- Disconnect Power: Ensure all power to the installation area is turned off at the circuit breaker or fuse box.
- Mounting: Position the motor using the thru-bolt mounting option. Securely fasten the motor to the mounting surface using appropriate bolts and nuts. Ensure the motor is level and stable to prevent vibration.
- Electrical Connection:
- Identify the motor's electrical leads. The motor operates on 115 Volts.
- Connect the motor's wires to the power supply according to local electrical codes and the wiring diagram of your specific application. Ensure all connections are secure and insulated.
- Verify proper grounding.
- Shaft Connection: Connect the driven component (e.g., fan blade) to the motor shaft. Ensure it is securely fastened and balanced to prevent vibration and premature wear. The shaft dimensions are 3/8 inch diameter by 2-3/4 inches length.
- Final Check: Double-check all connections, mounting, and ensure no obstructions are near the motor's moving parts or ventilation openings.
Operating Instructions
Once installed, the Packard 90420 motor is designed for straightforward operation.
- Power On: Restore power to the circuit.
- Initial Start-up: Observe the motor during its first few minutes of operation. Listen for unusual noises, check for excessive vibration, and ensure the shaft rotates freely in the correct direction (CWSE).
- Continuous Operation: The motor is designed for continuous duty within its specified ratings. The automatic overload protection will trip if the motor is subjected to excessive load or temperature.
Note: This motor is permanently lubricated and sealed, requiring no external lubrication during its lifespan under normal operating conditions.
Maintenance
The Packard 90420 motor is designed for low maintenance. However, regular inspection can extend its lifespan and ensure optimal performance.
- Periodic Inspection: Annually inspect the motor for signs of wear, damage, or corrosion.
- Cleanliness: Keep the motor's exterior and ventilation openings free from dust, dirt, and debris. A build-up can impede cooling and lead to overheating. Use a soft brush or compressed air for cleaning.
- Wiring Check: Periodically check electrical connections for tightness and signs of insulation degradation.
- Vibration Check: Excessive vibration can indicate an issue with mounting, the driven component, or internal motor problems. Address any significant vibration promptly.
Do not attempt to disassemble the motor. There are no user-serviceable parts inside.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power supply Tripped overload protector Faulty wiring | Check power source and circuit breaker. Allow motor to cool; reduce load if overloaded. Inspect and secure all electrical connections. |
| Motor overheats | Blocked ventilation Excessive load Incorrect voltage | Clean motor and ensure clear airflow. Reduce mechanical load on the motor. Verify power supply is 115V. |
| Excessive noise or vibration | Loose mounting Unbalanced driven component Worn bearings | Tighten mounting bolts. Balance or replace the driven component. Motor may require replacement if bearings are worn. |
If troubleshooting steps do not resolve the issue, contact a qualified technician or Packard customer support.
