JSS57P2N integrated closed loop stepper motor is all-in-one closed loop stepper system which integrates closed loop stepper motor with digital driver. Servo control and digital stepper driving technology are perfectly merged into this smart system. Optical encoder with high speed position sampling feedback of 50μs built inside, can help system avoid losing-step, greatly improve low-speed instability and reduces noise. This Series products have the advantages of both stepper and servo, features in low heat, smooth motion, fast response, high speed and big torque output.Features:Integrated compact size for saving mounting space.Small vibration, Smooth and reliable moving at low speed.Selected preci-sion components, adopt fine quality copper casting coils, low heating, high efficiency, silent, can provides long service time.Position error correction and never lose steps.Over-current, over voltage and position ultra difference protection function.Quickly response and perfect acceleration, high torque at high speed.Automatic current adjustment based on load, lower temperature rising.Pulses response frequency can reach 200KHZ.16 kinds micro steps choice, highest 51,200 stepper motor.Drive nema 23 series 2N.m closed loop stepper motor.Specifications:Name: Stepper MotorStep angle: 1.8°Voltage range: DC24V-50VCurrent: 4.2AResistance: 1.8 mH±20%Holding torque: 2.0N.mMotor length: 76mmEncoder resolution: 1000 PPRItem weight: 1200g / 2.65lbPackage size: 210 * 110 * 125mm / 8.27 * 4.33 * 4.92inPackage weight: 1320g / 2.91lbPackage list:1 * Stepper Motor
