Re: Cim AND FisherPrice?

WHICH FP?

The FP 00801-0673 is a 290W motor.
The FP 00968-9015 is a 180W motor.
The FP 00968-9013 is a 170W motor.

You are pairing this with a CIM which is a 340W motor.

SO... you can match the free speeds but if you do, then at high loads, the FP will be struggling more than the CIM (for struggling read closer to its stall torque... ...which means more heat generated which when coupled with the fact that the 550 series can of a FP has much much less surface means HOT HOT HOT -- actually, since I think the FPs have thermal protection these days, means that the motor will be cutting out at high loads).

OR... you can match stall torques but if you do, then at low loads (i.e. free speeds) the FP will be slowing down the CIM.

BUT... you can't do both.

Lower power means that you have to give up on something.
