What happens when you pour water on an induction motor

Pouring water on an Induction Motor may stop it working, due to the lowering of the insulation resistance of the internal motor coil windings. The coil windings are located inside the metal case of the induction motor, and are what generates a magnetic field, which makes the motor turn. This article will focus on what […]

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 […]

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

Marine Induction Motor Servicing Tips Safety & Isolation of supply of induction motors. 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 […]

How to Reverse the Direction of a Three Phase Induction Motor

How to reverse the direction of a three-phase induction motor. To reverse a three phase induction motor, swap over any two of the three ‘phase’ connections in the motor terminal connection box. Warning:  Only attempt to do this if you have been trained, as over 400 volts is involved.  Also obtain all necessary ‘Permit To […]
