    2.5K Ω , AC motor, actuator

    The old style clocks had such a device to ensure they ran Clockwise at start up, often the spring would fail and Time would run backwards!

    Single phase motor - wiring questions

    They are separate windings, but the common of each is often connected to the neutral point in the case of a uni-directional motor, if the motor is to be reversed, the windings are separated in order to reverse one WRT the other. The centrifugal SW should be connected in series with the start...

    Single phase motor - wiring questions

    If the motor is made or intended for uni-directional, then that would be normal for the ends of both windings to be connected. BTW it is a start winding switch, not a run winding switch, the run winding would normally be connected all the time.

    Single phase motor - wiring questions

    The supplier should be able to tell you the values. It is reversed by changing relative polarity of the windings, i.e. reverse either the start or the run winding.

    Single phase motor - wiring questions

    If you can distinguish two separate coil windings, the higher resistance one should go to the Centrifugal SW, the other to the Run winding. The start capacitor would be in series with the start switch, (high res winding). How many caps did it come with? I assume the motor is reversed when in...

    Small motor with 104 cap bridge between terminals.

    The cap does nothing to aid rotation, it is a DC motor, NOT an Induction motor, completely different animal. Your drive circuit is obviously very sensitive to the brush noise generated by the commutator if it requires a cap in order to run..

    Peak Power and Nominal power of motor

    In a general sense, yes. As an example, a servo drive, which is usually programmable, the continuous current rating is set by either a pot or a parameter and this allows the drive to operate in a continuous manner within this setting, the other setting is peak current where if the continuous...

    Peak Power and Nominal power of motor

    Basically the voltage controls rpm, the torque is a result of current, In the continuous torque range, This operating current will not damage the motor, once this constant current range is exceeded, damage to the motor and/or drive can occur, if the duration is more than the rated spec.

    Peak Power and Nominal power of motor

    Of course that is possible, inertia has effect as RPM increases. What particular applications are these questions applied to specifically? Or is it just in general?

    Peak Power and Nominal power of motor

    This also generally applies to motor controllers, they also have a continuous torque rating, as well as a momentary peak rating where this peak can only occur for a very brief period without causing damage to the drive. And this same torque (current) criteria also applies to the motor.

    Small motor with 104 cap bridge between terminals.

    Possibly, but I would not expect failure at ~ 12v operating voltage. A resistance test, also a Diode range test on the cap might show it up? If this was intended as noise suppression, I would have though the typical reverse biased diode snubber would have been better, the application only uses...

    Charging cap with three phase

    He'd depleted all his 'spent' up energy! :D:p

    Small motor with 104 cap bridge between terminals.

    I am still not convinced that the motor requires the cap in order to run, the Manuf spec sheet show it as a DC motor and do not specify any kind of cap needed, the only thing they show is a varistor suppressor can be used across the terminals. If a cap was required, I would expect to see this...

    Quite a few of us belong to both! :cool:

    Small motor with 104 cap bridge between terminals.

    Quite a few sources for the motor e.g. Jameco have them for $4.00ea !
