Typical applications
What an integrated stepper motor is
An integrated stepper motor combines a hybrid stepper, its drive and often a motion controller in a single housing, sometimes with an encoder for closed-loop operation. The unit connects directly to a DC supply and a command interface, which may be pulse and direction, analogue, Modbus, CANopen or industrial Ethernet. Integration removes the separate drive and motor cable, reducing cabinet space and wiring, and some units can store and run simple motion programs on their own.
When engineers choose an integrated stepper motor
Choose an integrated stepper for compact or distributed machines with many small axes, such as format changeover, laboratory automation and small conveyors. Fewer components simplify assembly and reduce wiring faults. The trade-offs are heat and flexibility: electronics on the motor raise local temperature, and the whole unit is replaced on a fault. For high-power steppers or hot environments, separate drives are usually more practical.
How to specify the Leadshine iCS Series
Send these with your enquiry and an engineer can confirm the right Leadshine iCS Series variant:
- Holding torque and torque at speed (Nm, rpm)
- Frame size (NEMA or mm)
- Supply voltage (V DC)
- Control interface and protocol
- Open or closed loop
- I/O count and stored program capability
- IP code and ambient temperature (°C)
Common mistakes to avoid
- Mounting in a hot spot and derating the electronics
- Choosing the wrong protocol variant for the controller
- Ignoring cable routing and connector orientation
- Overlooking supply sizing for many axes at once
Leadshine iCS Series: frequently asked questions
What is the Leadshine iCS Series?
Closed-loop integrated stepper (motor, 14-bit encoder and drive) with pulse/direction input, NEMA 17-24 up to 3.5 Nm. Published series figures include current 7 A, holding torque 0.3 Nm, holding torque 3.5 Nm. It is available through our supply network, and our engineers can confirm the right variant for your application.
Who makes the Leadshine iCS Series?
The Leadshine iCS Series is made by Leadshine (Leadshine Technology) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the current of the Leadshine iCS Series?
The published series maximum current is 7 A. Individual models and sizes in the Leadshine iCS Series range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
What are the benefits of an integrated stepper motor?
An integrated stepper reduces wiring, cabinet space and assembly time because the drive is built into the motor. It also shortens motor cables, which helps EMC. This suits distributed and modular machines with many small axes. The trade-off is that the electronics share the motor environment.
Can an integrated stepper run without a PLC?
Many integrated steppers can store simple motion programs and respond to digital inputs, so they can run standalone for basic tasks such as indexing or speed control. For coordinated multi-axis machines, a PLC or motion controller usually commands them over a fieldbus.
