motor 1

[Kuldipkenya]

I have a dough mixer. The motor burnt out. The motor is rated -1.5hp 1400rpm single phase, 220v perm capacitor . The name plate reads 1.6 amps.IP44.
I want to replace the motor. Should i use Cap Start Cap Run motor or should i just stick to the original permanent cap motor. This is a large catering mixer.

Thanks

PSC motors tend to have less starting torque than cap start, so if the machine was originally designed by the factory for a PSC motor, another type may present damaging torque on starting. On the other hand if the motor was erroneously replaced with the wrong type, that may be why it failed. You really need to ask this of the machine mfr, if they are still around. If not, try to find similar machines from the same mfr and see what they use.

You can make such a substitution if a higher starting torque of the new motor will not do any harm. Otherwise, my opinion is that single-phase motors should be avoided wherever possible.
BTW, whether the current is 1.6 Amps?

Good point. FLA cannot possibly be that low for 1.5 hp 220vac single phase.

Maybe a 1/4 HP or 1/3 HP motor in place of the original 1.5 HP??
Simple arithmetic (1 HP = 750 Watts) indicates a little less than 1/2 HP, but the poor power factor and poorer efficiency of these small motors suggests the lower estimates.
Perhaps the original motor was replaced with a too small motor of the wrong type. I have installed a couple of industrial dough mixers. As I remember the motors were quite robust particularly in regards to starting duty.

Thanks everyone.
I spoke to the manufacturers and they say the motor is the right size. The stamping for the amps is wrong. It should be perm cap as the starting should not be too powerful .Otherwise the drive chain could snap.
Thanks once again.

Thank you for the update Kuldipkenya.
