Well-known and widely used programmable stepper motor controllers SMSD-LAN series are now available with the Modbus TCP communication protocol. Like the basic model, there are two version with Modbus TCP: SMSD-4.2LAN-Modbus (current per phase up to 4.2A) and SMSD-8.0LAN-Modbus (up to 8.0A).

Motors, actuators, motor drivers and controllers can now be purchased in our new online store shop.smd.ee

BMD-5DIN is a speed controller for DC brush motors up to 5A. The controller is cheaper than the base 20A version and it can be successfully used in the most low power systems. Motor speed is regulated by analog signal or can be adjusted by an internal potentiometer. To prevent motor overloading, the speed controller provides current limitation function.

SMSD-4.2LAN and SMSD-8.0LAN stepmotor controllers available for order.

We have updated the stepper motor controllers SMSD-1.5Modbus ver.2 and launch new 4A and 8A modifications. Now the new models SMSD-1.5Modbus ver.3, SMSD-4.2Modbus and SMSD-8.0Modbus are already on sale.

We have updated our popular stepper motor drivers SMD-4.2DIN ver.2 and SMD-8.0DIN ver.2. Serial production has already begun and the drivers are ready to be ordered. New models SMD-4.2DIN ver.3 and SMD-8.0DIN ver.3 provide more efficient stepper motor control - better dynamics and high positioning accuracy.

We’re excited to announce that Smart Motor Devices OU will be attending the Smart Production Solutions (SPS) international exhibition for industrial automation in Nuremberg, Germany from 8‑10 November 2022! Meet us at our stand (Hall 4/126)!

New product line: frameless stepper motor drivers (open frame versions) and drivers in an open housing with DIN clamp (carrier kit version). Drivers are available in four modifications - with a maximum phase current of 1.6A, 2.8A, 4.2A and 8.0A.

Firmware of BLDC controllers has been updated. We added Mathematical and logical operations, increased the number of auxiliary registers. Also now it is possible to operate with 32-bit data. Another improvement is four quadrant speed control - now the direction of the load does not affect the stabilization of the motor speed.

Firmware of DC brush motor controllers has been updated. Mathematical and logical operations, as well as work with 32-bit variables have been added to the functionality of the controllers.

New version of DC motor controllers is ready. New methods of speed control were added to the new model BMD-20DIN ver.2

The new version is close to release. We have added the function of debugging of user programs. Now it is even easier to make operation algorithms.

BLDC motor controllers BLSD-20Modbus has been updated for four-quadrant speed control. Now speed control is precise and doesn't depend on load direction.

Functionality, firmware and software for stepper motor controller SMD-4.2DIN ver.2 has been updated. New version is available now.

New version of firmware provides better thermal protection functionality.

The BLDC motor controllers BLD-20DIN were updated to operate with high speed brushless motors. Now the maximum motor speed and velocity regulation sensitivity can be adjusted by a customer.

We have completed new revision and launched the production of the first batch of updated stepper motor controllers SMSD‑4.2RS with RS‑232 and RS‑485 interfaces.

A new version of the software «Modbus Special Utility» for DC brush controllers BMSD-20/40Modbus and BLDC controllers BLSD‑20Modbus has been released.

Updating of SMSD‑LAN stepmotor controllers firmware has been started in order to adopt it to TCP/IP Modbus communication protocol.
