What happens when you get a three phase Induction Motor wet

Flooded or Wet Induction Motors First of all, try not to! When designing a marine of industrial installation, you need to consider the IP, or ingress protection rating of your Induction motor. By choosing a motor with a high enough IP rating, it is possible that when you submerge your Induction Motor, nothing will happen. […]

Single Phasing In Three Phase Marine Induction Motors

Single Phasing Faults In Marine & Land Induction Motors Single phasing is the term used when one of the three stator windings in an induction motor is not ‘energised’. Three reasons for this happening in a Marine (& Land) environment are:- Mechanical vibration – causing the terminal nuts to become loose, and therefore disconnecting a […]

Tips for Servicing Marine & Land Based Induction Motors

Safety & Isolation of supply of induction motors. First tip, taking a casual approach to electricity can prove fatal. This is especially true when we are talking about three-phase motors, as they operate in the UK & EU at 400 Volts Alternating Current (400 VAC). Marine installations typically operate at an even higher 440 Volt […]

Transformers – The Different Types of Electrical Transformers

Transformers The Different Types of Transformers Transformers either ‘step up’ or ‘step down’ AC voltage. They do do by magnetic induction. Step Down types reduce the voltage coming out, compared to the voltage going in. These are the most common type. Step Up types have a higher output voltage than an input voltage. These are […]

How to Reverse the Direction of a Three Phase Induction Motor

How to reverse the direction of a three-phase induction motor. Reversing the direction of a three phase Induction Motor is useful in a number of situations. For example in a electric winch or elvevator (lift), there is a requirement for the motor to reverse. To reverse a three phase induction motor, swap over any two […]

Phasing Out – Three Phase Induction Motors – on ships

Phasing out a Three Phase Induction motor, onboard ships (or on land)  is the process of identifying both ends of each of the three stator coils (3 phase motor). 'Phasing Out' pic.twitter.com/RMLqyjbs0u — Craig Miles (@acraigmiles) October 17, 2016
