Relays
What is a Relay?
Relays are electrically operated switches that open and close circuits receiving electrical signals from external sources. The relays built into electrical products work in a similar way; they receive an electrical signal and send the signal to other equipment by turning the switch on and off. The three main functions of relays are to allow a small amount of electrical current to control high current loads, send different types of electrical signals, and drive multiple outputs with just one input.

Crouzet AC Synchronous and DC Stepper Motors for All Needs
AC Synchronous Motors
AC Synchronous Motors are the best solution for applications that require constant movement and a low torque, like in in medical equipment, valves, pumps and water treatment. Their rotation speed is directly proportional to the supply frequency, that means it’s always constant and independent from the load.
DC Stepper Motors
DC Stepper Motors are a great choice for simple applications that require long durability and easy integration, like small HVAC systems, photocopy machines, plot-ters, medical pumps and drip feeders, or vending and gaming machines.
Gearboxes
To meet the perfect speed and torque levels for the great majority of applications, we offer a complete range of gearboxes, with a wide variety of ratios, for adjusting our motors.
Each gearbox has been designed for a specific workload and optimized for a long mechanical life, with a big capacity to absorb the maximum torque in continus movement.
