Stepper Motor

The Leadshine DM542 Digital Stepper Motor Driver is an economical micro-stepping driver based on the patented technology of Leadshine. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.

By using the advanced bipolar constant-current chopping technique, it can output more speed and torque from the same motor, compared with traditional drivers, such as L/R drivers. Its 3-state current control technology allows coil currents to be well controlled and with relatively small current ripple, therefore less motor heating is achieved.

The DM542 is a fully digital stepper driver developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offer a quick setup to optimal modes with different motors.

Compared with traditional analog drives, DM542 can drive a stepper motor at the much lower noise, lower heating, and smoother movement. Its unique features make DM542T an ideal choice for high requirement applications. We highly recommend this to work as NEMA 17 driver and NEMA 23 driver.

We have the range of motor drivers particularly compatible with Servos, Stepper Motors and DC Motors, do not forget to check them

Nema17 4.2 kg-cm Single Shaft Stepper motor can provide 4.2 kg-cm of torque at 1.7A current per phase. The stepper motors move in precisely repeatable steps, hence they are the motors of choice for the machines requiring precise position control.

The motor’s position can be commanded to move or hold at one position with the help of Stepper Motor Drivers. The Nema17 4.2 kg-cm Stepper motor provides excellent response to starting, stopping and reversing pulses from stepper motor driver.

They are very useful in the various application, especially which demands low speed with high precision. Many machines such as 3D Printers, CNC Router and Mills, Camera Platforms, XYZ Plotters etc.

It is a brushless DC motor, so the life of this motor is dependent upon life of the bearings. The position control is achieved by a simple Open Loop control mechanism so doesn’t require complex electronic control circuitry.

The motor’s shaft has been machined for good grip with a pulley, drive gear etc. and especially avoiding stall or slip.

Features of NEMA17 4.2 kg-cm Single Shaft Stepper Motor:-

• Input pulse decides the rotation angle of the motor.
• High accuracy of around 3 to 5% a step.
• Provides good starting, stopping and reversing.
• Control of this motor is less costly because of the exclusion of complex control circuitry.
• The speed is proportional to the frequency of the input pulses.
