If your network is 50 Hz, a 12-pole motor will be 500 synchronous rpm, and an 8-pole motor will be 750 rpm. If they are induction motors, they will run slightly slower, owing to slip.

Contact motor distributors locally, and give them some idea of the power range required and the application as well as the speed.

  • A 12VDC instrument motor doing 500-750rpm and pulling a few tens of mA would cost about £35GBP, whereas a 50kW motor for 415VAC doing 500-750rpm might be several £thousand.

Motor selection requires HP, RPM, Voltage etc.
So your are silent on other two.
So AC motor with 750RPM is available.
Synchronous motors available with 500RPM and less

Mr.Vishu 91,

Your query is just like a child's which asks for a choclate ( Sorry for the

comment).

If you are serious to get a technically correct reply you are to give the following details.

(1) What is the duty of the motor- Continous or intermittant or stand by.

(2) The voltage available at your site.Frequency ( India 50 Hz)

(3) The local enviornment- Moist, Humid, Hot, Rainy etc so that you can

choose the type of enclosure- TEFC, TEDP,

(4) What is the area available- at lower speeds - motor dia may be more.

(5) Who is the vendor - will he give after-sales service.

(6) Natue of the load- Starting with loads- like Conveyor belts-Hoist

applications.

(7) Get a B2B directory and search for motor manufacturers, dealers,talk to

them- than wasting our time ( spoon feeding will expose your

idleness and reluctance to use your brain and time).
