Hi,
have a look on the label, the max sustained torque is on it. Aside from any thing else there is the power spec...power=torque x speed....easy.
The Allen Bradley MPL series are mid to low inertia.....the A in A310P stands for 230V, the 3 is the frame size, 80 mm square, the 10 refers to the length or
stack size and P refers to the speed, 5000 rpm is this case. The A310P in the first link is 730W. There is an A320P model of 1.3kW and the second motor I
linked is an A330P of 1.8kW.
The rated torque of the three models is:
1) A310P 1.58Nm
2) A320P 3.05Nm
3) A330P 4.18Nm
The motor I used is the A330H model which is rated to 3500 rpm but has a little more torque, 6Nm which suited me I want plenty of torque, but still 1.8kW.
You may note that the rated current of the small motor the A310P is just under 5A. You could use a smaller drive than the link I posted, the 2098-DSD-010
has rated current of 5A, overload 15A,(5/15A) and would run the A310P nicely.
The larger two will require more current, the 2098-DSD-020 is rated at 10/30 A. I used this to power my motor although if I could have found a 2098-DSD-030
rated at 15/30A I would've taken it. The larger the drive the more you pay. The 010 can be had for under $100 but $100-$200 is more realistic. The 020 can be
had for just over $100 but $200-$400 is more realistic. I missed out on an 030 for $280, $500-$800 is the norm.
The 730W motor and drive could be had for about $500 plus shipping. Whether you consider that good value for secondhand I don't know. Some of the
Chinese offerings are about the same but new. I ended up paying $700 NZD, about $500US for the motor, $250US for the drive and $150 for the cables,
near enuf to $1000 for a 1.8kW servo and drive. It kicks anus!!! I am happy that the value is there, the crappiest I was prepared to go was Delta and they
cost more in this power range.
Go to the Rockwell Automation site and get the MPL series drawings a see if you cant squeeze one into your machine, they are good.
