These guidelines help with selecting a drive using the Automated Part Selector.

Under specifying a product results in too many drives to choose from. Over specifying a product results with no products found. Start your search by specifying the current and voltage rating of the drive

Current

Continuous Output Current

This field specifies the continuous current rating of the drive, not the continuous current rating that you need for your system. This is an important distinction because most AMC drives fall within certain values.

For this section enter the continuous current rating that you need for your system in “At least”. Then for “No more than” enter a value that includes the next current level in the list below.

3, 5, 6, 7.5, 8, 10, 12.5, 15, 20, 30, 50, 60

To increase the number of results continue to select the next higher value in the list.

For example. Your motor is rated to 10.5A continuous. Therefore enter “At least” 10.5A and “No more than” 12.5A. If you need to widen the search go to the next current level in the list (15A).

Voltage

Depending on how you want to supply power to your drive follow the instructions for (DC) or (AC) below.

Supply Voltage (DC)

Refers to DC power supply voltage.

Enter the output voltage of your power supply in both "At least" and "No more than." To widen the search, increase the range in 5V increments.

Example: If you have a 48V power supply then enter “At least 48V”, “No more than 48V”.

Supply Voltage (AC)

Refers to AC supply voltage.

Start by entering the same number for “At least” and for “No more than”. To widen the search increase the range in 5V increments.

Example: If you have 120VAC then enter “At least 120”, “No more than 120”.

Other Specifications

Other important specifications for drive selection are:

Drive Specifications: motor type

"DC Brushed" will include almost every drive in AMC's catalogue since brushless drives can also drive brushed motors.

"DC Brushless", "DC Servo", "AC Servo/Brushless" and "Linear Motor" all select the same type of drive - drives that power brushless motors.

Motor Feedback

Choose only feedback devices that are intended to go back to the drive. Typically for commutation, velocity and position purposes.

Example: A drive needs Hall sensors for commutation and the encoder will go to the controller for position and velocity feedback. In this case just select Hall sensor feedback.

All other choices

The other choices are fairly self explanatory. Just remember not to over specify!
