A drive motor can also act as a generator. If the drive system is built so as to allow reverse power to flow then this power can be fed into a resistor, thus taking energy out of the system and causing whatever is driving the motor to slow down. Following to this the braking resistor converts the stop energy into heat. Electrical drive systems are being used more and more on ships, oil rigs, crane barges and offshore vessels of all types. An important benefit from using an electric drive is that reliable systems of regenerative and dynamic braking resistors are available to complement or replace traditional mechanical braking systems. The advantages of electric braking include control, reliability, mechanical simplicity, weight saving and in some cases the opportunity to make use of the regenerated braking energy. The Braking Resistor Units from Klöpper Therm are designed according to specific applications.

CSN® Braking Resistors are used for controlled braking of every kind of electrical drives. Braking resistors convert the energy of drives into thermal energy which will be dissipated into the corresponding cooling medium. Design variations with natural or forced air cooling are available. CSN® Braking Resistors can be delivered with an indirect water cooling system using an airwater heat exchanger as well. The design of the CSN® Braking Resistors is particularly suitable for use in maritime applications. Schniewindt, as global market leader in this resistor sector, has a wealth of experience in the design according to the technical guidelines and rules of international classification societies for example

The SMD‑4.2DIN ver.2 driver is designed to control two and four-phase hybrid stepper motors with a phase current of up to 4.2A. The unit provides for mounting on a DIN rail, which is convenient for placing it in a production environment. Due to its advanced design, the SMD‑4.2DIN ver.2 delivers dynamics that accelerate the stepper motor to over 1000 rpm in a fraction of a second and easily reach operating speeds of over 4000 rpm while maintaining enough torque to perform useful work For stepper motor operation with high inertia load, a connector is provided for connecting an external braking resistor. The SMD‑4.2DIN ver.2 driver provides both pulse position control and analog speed or angle control. Microstepping mode - 1, 1/2, 1/4,1/8, 1/16, 1/32, 1/64, 1/128 Control methods: - Pulse position control (STEP/DIR) - Analog speed control (0 ‑ 5 VDC or potentiometer) - Analog control of rotation angle - tracking mode (0 ‑ 5 VDC or potentiometer) - Constant speed rotation
