Stepper Motor Driver for NEMA 17 NEMA 23 Motor

Stepper Motor Driver Specifications:1 High performance, low price 2 voltage 18V-50VDC. 3 For neam23 and nema17 motor 4 less than 4.2A current 5 300g weight Stepper motor driver: Introduction: M542MA is a type of two-phase hybrid stepping motor driver, the drive voltage of it is from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts Is smiliar to the circuit of servo control which enables the motor run smoothly almost without Noise and vibration. Holding torque when M542MA run under high speed is also significantly Higher than the other two-phase driver, what's more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on. Features: L High performance, low price L Average current control, 2-phase sinusoidal output current drive L Supply voltage from 18VDC to 50VDC L Opto-isolated signal I/O L Overvoltage, under voltage, overcurrent, phase short circuit protection L 15 channels subdivision and automatic idle-current reduction L 8 channels output phase current setting L Offline command input terminal L Motor torque is related to speed, but not related to step/revolution L High start speed L High hording torque under high speed Input voltage18-50VDCInput current< 4AOutput current1.0A~4.2AConsumptionConsumption:80W;  Internal Insurance:6ATemperatureWorking Temperature -10~45°C; Stocking temperature -40°C~70°CHumidityNo condensation, no water dropletsgasProhibition of combustible gases and conductive dustweight300G  Function choice ( Using DIP pins to achieve this function) 1) Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table:   SW5OFFONOFFONOFFONOFFONOFFONOFFONOFFONOFFSW6ONOFFOFFONONOFFOFFONONOFFOFFONONOFFOFFSW7ONONONOFFOFFOFFOFFONONONONOFFOFFOFFOFFSW8ONONONONONONONOFFOFFOFFOFFOFFOFFOFFOFFPULSE/REV400800160032006400128002560010002000400050008000100002000025000    2 Closest to your motor's required current    Output current (A)SW1SW2SW3PEAKRMSONONON1.000.71OFFONON1.461.04ONOFFON1.911.36OFFOFFON2.371.69ONONOFF2.842.03OFFONOFF3.312.36ONOFFOFF3.762.69OFFOFFOFF4.203.00      Pins of motor & power:   Motor and power pins1A+Motors wiring 2A-3B+4B-5,6DC+ DC-Power supplyPower supply :DC18-50VDC1  Company Capacity 1.

FAQ(Q=Question, A=Answer)Q: What's your main products?A:We currently produce Brushed Dc Motors, Brushed Dc gear Motors, Planetary Dc Gear Motors, Brushless Dc Motors, Stepper motors and Ac Motors etc. You can check the specifications for above motors on our website and you can email us to recommend needed motors per your specification too. Q:How to select a suitable motor?A:If you have motor pictures or drawings to show us, or you have detailed specs like voltage, speed, torque, motor size, working mode of the motor, needed life time and noise level etc, please do not hesitate to let us know, then we can recommend suitable motor per your request accordingly. Q: Do you have customized service for your standard motors?A:Yes, we can customize per your request for the voltage, speed, torque and shaft size/shape. If you need additional wires/cables soldered on the terminal or need to add connectors, or capacitors or EMC we can make it too. Q :Do you have individual design service for motors?A:Yes, we would like to design motors individually for our customers, but it may need some mould charge and design charge.  Q:Can I have samples for testing first?A:Yes, definitely you can. After confirmed the needed motor specs, we will quote and provide a proforma invoice for samples, once we get the payment, we will get a PASS from our account department to proceed samples accordingly. Q:How do you make sure motor quality?A:We have our own inspection procedures: for incoming materials, we have signed sample and drawing to make sure qualified incoming materials; for production process, we have tour inspection in the process and final inspection to make sure qualified products before shipping. Q:What's your lead time?A:Generally speaking, our regular standard product will need 25-30days, a bit longer for customized products. But we are very flexible on the lead time, it will depends on the specific orders Q:What's your payment term?A:For all our new customers, we will need 40% deposite, 60% paid before shipment. Q:When will you reply after got my inquiries?A:We will response within 24 hours once get your inquires. Q:How can I trust you to make sure my money is safe?A:We are certified by the third party SGS and we have exported to over 85 countries up to June.2017.
