TECO Instruction Manual

Squirrel Cage Induction Motors

Whilst Motors are installed awaiting commissioning they must be adequately

protected against the elements, all external components in particular the shaft

extension and external labyrinth seals at the drive end must be fully covered

to avoid water ingress entering the motor body whilst stationery.

Please ensure that both the non drive end and drive end antifriction bearings

are fully purged with sufficient grease at first start up/commissioning

with the recommended grade and quantity of grease.

Why is my TECO AEJE motor overheating?
- S
  Steven TurnerAug 15, 2025
  If your TECO Engine motor is overheating, it could be due to several reasons. Possible causes include overload, intermittent overload, under-voltage, over-voltage, a clogged ventilation duct, ambient temperature exceeding 450C, friction between the rotor and stator, a blown fuse (resulting in single-phase rotation), poor contact in circuit switches or the starting switch, or an unbalanced three-phase voltage. You can lighten the load, check the circuit capacity and power source, remove any foreign matter in the duct, lower the ambient temperature, repair any friction issues, install the specified fuse, and check and repair circuit switches. If there is an unbalanced three-phase voltage, check the circuit or consult the power company.

What to do if the fuse keeps blowing in my TECO AEJE Engine?
- B
  Brandon BrownAug 19, 2025
  If your TECO Engine experiences a fuse blowing, circuit breaker tripping, or a slow start accompanied by electromagnetic noise, it may be due to a short circuit, incorrect wiring, poor contact in circuit switches, broken wiring, poor contact of the starting switch, or an incorrect connection of the starting switch. To address this, check the circuit and wiring, and check and repair any poor contacts or broken wiring.

How to troubleshoot a TECO Engine that fails to start without load?
- J
  Jennifer MillerAug 21, 2025
  If your TECO Engine fails to start without any load, it could be due to several reasons: the power may be off, the switch may be off, there might be no fuse installed, the wires could be broken, the lead could be broken, or the winding might be faulty. To resolve this, consult the power company, switch the device on, install a fuse, and check and repair any broken wires, leads, or faulty winding.

What to do if my TECO AEJE Engine overloads after starting?
- J
  Jennifer GarrettAug 25, 2025
  If your TECO Engine is experiencing overload after starting, it might be due to insufficient capacity of the fuse or breaker, a general overload, or a high load at low voltage. To solve this, replace the fuse or breaker with one of adequate capacity, lighten the load, and check the circuit capacity while reducing the load.

Why is the switch on my TECO AEJE Engine overheating?
- J
  Jackie BakerAug 28, 2025
  If your TECO Engine switch is overheating, it could be due to insufficient capacity of the switch or a high load. To resolve this, replace the switch with one of adequate capacity or lighten the load.

What causes bearing overheat in a TECO Engine?
- L
  Lisa GutierrezAug 30, 2025
  If your TECO Engine bearings are overheating, it could be due to misalignment between the motor and the load, not enough grease, or high bearing noise. To address this, realign the motor and load, fully purge the bearings with grease, or replace the damaged bearing.

What causes mechanical vibration in my TECO AEJE?
- D
  Debra MillsSep 3, 2025
  If your TECO Engine is experiencing mechanical vibration, it could be due to a broken fan blade, unsymmetrical centers between the belt sheaf, central points of couplings not lying on the same level, improper mounting installation, or a motor mounting bed that is not strong. To address this, replace the fan, align the central points, adjust the central points of couplings to the same level, lock the mounting screw, or reinforce the mounting bed.

Why is my TECO Engine making a sudden sharp noise and smoking?
- D
  David RossSep 6, 2025
  If your TECO Engine is producing sudden sharp noise and smoking, it could be due to a short circuit of windings, not enough grease, deterioration of grease, or excessive noise. To resolve this, repair the short circuit, fully purge bearings with grease, clean and re-grease the bearing, or replace the damaged bearing.

What causes electro-magnetic vibration in my TECO Engine?
- D
  Deborah PetersenSep 9, 2025
  If your TECO Engine is experiencing electro-magnetic vibration, it could be due to a short circuit of windings. To address this, repair the short circuit.

How to fix mechanical noise caused by machinery in my TECO AEJE Engine?
- M
  Mrs. Michelle CooleySep 12, 2025
  If your TECO Engine is producing mechanical noise, it could be due to a loose belt sheaf, loose coupling, loose screw, or fan rubbing. To resolve this, adjust the key and lock the screw, adjust the position of couplings and tighten them, tighten any loose screws, or adjust the fan position.
