Csl Motors MS

Series: Other models

The Csl Motors MS is a three-phase induction motor. The rated output is 0.75 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The rated voltage is 415 V. The housing is frame size 800 in foot-mounted form. The protection class is IP55. The efficiency is 75.5 per cent at full load, 75.5 per cent at 75 per cent load and 75.5 per cent at half load. The mounting arrangement to IEC 60034-7 is B3. The motor is built in China. The figures come from the Australian MEPS register under standard AS/NZS 1359.5:2004; measured to IEC 60034-2-1 (Edition 2.0). Rated output within this group ranges from 0.18 to 1,119 kW; the MS sits at the bottom of that range with 0.75 kW. Its immediate neighbours are the TTW01 below it with 0.73 kW and the 3514167 above it with 0.9 kW.

Csl Motors MS – a small three-phase industrial motor rated at 0.75 kilowatts for pumps, fans and simple drive tasks in workshops and trades

Motors such as the MS described here belong to the broad class of small three-phase industrial motors, built as standard series for pumps, fans and simple drive tasks in trades and building services.

With a rated output of 0.75 kilowatts, the motor sits at the lower end of the common series outputs typical of small pumps, fans or belt conveyors in workshops. The frame size stays small in this output range, usually with a shaft centre height well under 100 millimetres, which eases handling and transport.

In industrial motors of this kind the squirrel-cage rotor is standard, since it runs with little maintenance and needs no slip rings. The number of poles sets the synchronous speed: at 50 hertz, two-pole motors turn at 3,000 revolutions per minute, four-pole motors at 1,500 and six-pole motors at 1,000, each slightly reduced by slip. Protection ratings follow IEC 60529 and mounting arrangements IEC 60034-7, for example a foot-mounted IM B3 motor or a flange-mounted IM B5 type. Running it from a frequency inverter raises the demands on insulation strength.

When buying secondhand, the rating plate is worth checking first: output, voltage, frequency and connection type should be legible and suitable. Turned by hand, the bearings should run smoothly, without play or noise, while an insulation test with an insulation-resistance tester reveals damp or damaged windings. The fan cover and terminal box deserve a second look, since corrosion or broken ribs point to a hard working life. If the motor has been rewound, that is worth raising openly before buying.

Frequently asked questions

How much power does the Csl Motors MS have?

The Csl Motors MS delivers 0.8 kW.

What to check before buying

  • Match the data plate against the order: frame size, mounting and rating have to agree.
  • Check the ingress rating against the installation site — outdoors or in dust the demands differ.
  • Hold the mounting form and dimensions against the existing seat before ordering.
  • The pole count sets the speed — when replacing an older unit, compare this first.
  • For used units, ask about winding condition and bearing play.
  • Ask about parts availability for this series — the running costs hang on it.
