Description:

NEMA 34 850 oz/in 72 VDC Servo Motor
Skewed rotor design -These are actual servo motors, not just a DC motor with an encoder on it. The marked difference is in the skewing of the rotor resulting in very low cogging which makes these servos suitable for high resolution applications such as tight tolerance CNC machining. Like all of our motors, they are very well made.

The high quality HEDS-9100 optical encoder comes mounted on the rear shaft of the motor. The electrical specifications of these motors were devised to work specifically with Gecko drives but work with any brush type servo drives with appropriate electrical parameters.
Encoder Options: The encoder unit comes in standard plastic or with a protective metal housing. Both options are available with a choice of 250 or 500 lines.
The metal encoder housing is CNC machined, black anodized and comes completely installed with a convenient DB-9 Female connector.
Specifications:

•skewed rotorrdesign
• maximum operating speed: 4200 rpm
• continuous torque: 270 oz/in
• peak torque: 850oz/in
• torque constant (KT): .1757 N. m/am
• voltage constant (KE): 15.71 volts/100rpm
• terminal voltage: 72 DC
• continuous current: 8.5A
• peak current: 38A
• inductance: 2.35 mH
• resistance: 85 ohm
• weight: 8.8 lbs
• inertia: 3.39 g.cm^2
• 7 inches
• Shaft diameter is 1/2"

The scope trace shows how quickly the motor responds to a command to reverse from 400 rpm CW to 400 rpm CCW. The green trace is motor current taken with a Tektronix current probe. Note the current limiting at 21A. The yellow trace shows the position error in response to the instantaneous reversal command. The motor reverses direction and catches up to where it should be in less than 0.025 seconds. The motor generated 1058 watts (about 1.4 HP) while reversing in that brief period of time.
$235.00 with metal-housed encoder
$199.00 with standard encoder
$159.00 without encoder
