Crouzet expands its range of intelligent electric motors


Valence, January 24th 2019

SQ75 DCmind Brushless: brushless 600W motor with integrated electronics that knows no limit.

Thanks to its onboard intelligence, its safety functionalities and its communication capabilities, SQ75 offers new applications to Crouzet. This new member of the DCmind Brushless family is manufactured in France and is available in three versions from 310 W to 600 W.

High performance and sealed: dual winning combination

Crouzet has set its goal to technical excellence with SQ75. The starting point is high torque values, especially for the 310 W version, displaying a rated torque of 1 Nm (and a peak of 2.5 Nm; up to 6 Nm for the 600 W version!), over an extended speed range of up to 5,000 rpm. “SQ75 is thus capable of high rates of acceleration and deceleration, even for high inertia loads by means of its reject energy management module. A functionality that is useful for managing wheel braking of service robots in intralogistics environments” explains Michel Nicol, Business Engineer at Crouzet.

Unique on the market: the off-the-shelf SQ75 is water- and dustproof (except the shaft and front face), including in the 4.5 N.m version with holding brake and two levels of protection: IP671 and IP692, suitable for the most severe environments. “Combined with the most extended operable voltage range on the market (from 9 V to 75 V, on mains electricity and/or with battery), its level of seal enables us to propose SQ75 for service robotics: agriculture (agbots), logistics (AGV, AMR), defence (UGV), or even for industrial cleaning. Supplied with or without a gearbox and able to operate in autonomous mode or on a CANopen network, SQ75 can be used for other applications such as conveyor systems, packing machines or access control systems for vehicles or people” says Camille Machet (Offer Creation Marketing Motion for Crouzet), commenting on an analysis of SQ75.

Crouzet SQ75 DCmind Brushless Smart Power

A safe, smart and truly communicative motor

SQ75 operates with complete safety, by means particularly of its Safe Torque Off inputs, enabling the motor to be released, on a fully independent basis, from the microprocessor in the event of an emergency, for instance, on a machine integrated on a safety chain and requiring a special operation by a technician.

Thanks to its CANopen interface, SQ75 can be controlled in compliance with the CANBus standard. It can also operate entirely autonomously. Its intelligent functions (speed, position and torque control, pre-installed applications software) can also be configured using a simple USB key and DCmind Soft + CANopen Software, downloadable free of charge at These two communication configurations enable alert and usage data feedback by means of which users can create preventive maintenance functionalities.

Easy to install, operate and maintain

“Crouzet pays great attention to the integration of its products in its customers’ business environments, especially during installation, operation and maintenance phases” points out Camille Machet. This results in protection against wiring faults, initialization of the motor on the computer with a commercial USB cable, fine-tuning facilitated by DCmind soft + CANopen software (chart plotter, performance recorder, control loop tuning and error code feedback). What is more, the user has the possibility via the USB port of carrying out a local diagnosis of the motor while CANopen is running, and of checking the status of the communication with a LED incorporated</strong in the front face>.

Powerful, intelligent and easy to set up, SQ75 states its objective of falling in line with the trend of transformation of commercial control actuators towards “all in one” intelligent motors”.
