I recently bought a couple of these little motors to drive a small linear slide. The RC circuit calls for a 500 ohm resistor 5 watt (which is easy to find) and a .75 mfd 330v run capacitor (which is not so easy to find). What happens if a 1 mfd unit were substituted. How would it affect the...
I bought a bridge rectifier for this small motor armature and field. The rectifier is quite oversized at 600v and 60A. When connected to the standard 120v ac house source, the rectified voltage was 118v dc rather than 1.4X120V or 168 v like I expected. Motor and field voltage is 115v.
I tried...
Have a small DC shunt wound gearmotor. Nameplate shows 115vdc; armature current .33A.
If I measure the leads coming from the motor, I get 145 ohms for the armature, and 1268 ohms for the field.
Knowing that the field and armature are internally connected in parallel, I am wondering what the...
Have a small 1/50th shunt wound gearmotor with output speed of 57 rpm. I want to just run it at constant speed 57rpm output. I have a controller that is meant for a PM motor.
It has 90v dc out and a pot. Could I use this simple controller and connect both the armature and field to the 90 v...
