Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.

Typical applications
What a PCB-mount drive is
A PCB-mount stepper drive is a stepper driver module designed to be soldered or plugged onto a host circuit board. It contains the power stage and current control, and often a microstepping sequencer, accepting step and direction signals or serial commands. Some modules add a programmable motion controller. They let product designers embed stepper control into an instrument or device without a separate housed drive, saving space, cost and wiring.
When engineers choose a PCB-mount drive
Choose a PCB-mount stepper drive for compact products with stepper axes, such as laboratory analysers, medical devices, printers and small automation. It integrates with the product's electronics and supports volume production. The trade-offs are design responsibility and power: the host board must handle heat, protection and EMC, and current is typically limited to a few amps. For larger motors or industrial cabinets, a housed drive is simpler.
How to specify the Novanta IMS IM483H PLUS / IM805H PLUS
Send these with your enquiry and an engineer can confirm the right Novanta IMS IM483H PLUS / IM805H PLUS variant:
- Supply voltage (V DC)
- Phase current (A rms or peak)
- Microstep resolution
- Interface: pulse, serial or CAN
- Size and mounting
- Thermal design and heatsinking
- Protection features
Common mistakes to avoid
- Laying out the host board without copper area or a heatsink for the module
- Not adding protection against back-EMF and short circuits
- Using peak current ratings as continuous
- Leaving out EMC filtering
Novanta IMS IM483H PLUS / IM805H PLUS: frequently asked questions
Can you help replace Novanta IMS IM483H PLUS / IM805H PLUS or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Novanta IMS IM483H PLUS / IM805H PLUS?
Hybrid PCB-solder microstepping drivers: IM483H 48 V/3 A RMS and IM805H 75 V/5 A RMS, up to 51,200 steps/rev. Published series figures include current 7 A. It is available through our supply network, and our engineers can confirm the right variant for your application.
What model codes are in the Novanta IMS IM483H PLUS / IM805H PLUS range?
The Novanta IMS IM483H PLUS / IM805H PLUS range includes IM483H, IM805H. The table on this page lists each published model code with its key figures. Send us the code you use, or the one you need to replace, and our engineers will confirm availability, lead time or the closest equivalent.
Who makes the Novanta IMS IM483H PLUS / IM805H PLUS?
The Novanta IMS IM483H PLUS / IM805H PLUS is made by Novanta (Novanta Inc.) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the current of the Novanta IMS IM483H PLUS / IM805H PLUS?
The published series maximum current is 7 A. Individual models and sizes in the Novanta IMS IM483H PLUS / IM805H PLUS 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.
Is there an alternative to the Novanta IMS IM483H PLUS / IM805H PLUS?
We can assess suitable replacement options. On published figures, ADVANCED Motion Controls FlexPro Digital Servo Drives (FE, FX, FM, FD, FMP; Micro and Mini sizes) and Leadshine 2CS3E Series are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
What is the difference between rms and peak current on a stepper drive?
Peak current is the maximum instantaneous phase current, while rms is the effective value that sets heating. With microstepping sine currents, rms is roughly 0.71 times peak. Match the drive's setting to the motor's rated current and check which value the datasheet uses.
Do PCB-mount stepper drives need a heatsink?
At higher currents, yes. Heat is removed through the module's base or pins into copper areas on the host board and any heatsink. Current ratings typically assume specific thermal conditions, so check the datasheet's derating curve for your board and ambient temperature.
