Crouzet supplier in Romania
DC motors and compact electromechanical actuators
Founded in 1921 · Headquarters: Valence, France
Who is Crouzet and what does it make?
Crouzet is a French manufacturer of DC motors and electromechanical actuators, based in Valence and active since 1921. The motor range covers both brushed DC motors (32, 42 and 63 mm series) and brushless motors with position and speed control, used in equipment where mounting space is limited. We can quote from the Crouzet range of DC motors and actuators for compact automation equipment.
Crouzet targets niches with strict reliability requirements — aerospace, rail, medical — where motors must be certified to the standards specific to these industries. The brushless SMi21 and SMi22 series come with programmable position and speed control, with an encoder of up to 4,096 points, and the 63 mm brushed motors reach up to 104 W at voltages of up to 120V, with low-noise variants for noise-sensitive applications.
For Romanian integrators of compact equipment — medical machines, rail signalling systems or precision industrial equipment — Crouzet motors are relevant where reliability certification matters as much as the electrical parameters.
What do we supply from the Crouzet range?
| Product | Description |
|---|---|
| 57 mm Hall Effect Brushless Motors | Brushless direct-current motors with a 57 mm diameter. Typical application: compact automation equipment where long-term reliability matters more than initial cost. The customer must provide the required torque, the working speed and the available supply voltage. |
| SMi21 / SMi22 Programmable Motors | Brushless motors with programmable position and speed control, available in 57 mm diameter (SMi21, power 66-150W) and 75 mm (SMi22, power 310-600W), with an encoder of up to 4,096 points for precise positioning. Typical application: positioning actuators in medical or industrial equipment. The required positioning accuracy and the load torque are needed for correct selection. |
| 63 mm Series Brushed DC Motors | Brushed direct-current motors, 63 mm diameter, power from 27 to 95 W (standard version) or up to 104 W (low-noise version), at voltages between 12 and 120V. Typical application: equipment where operating noise must be limited, such as medical or office equipment. The customer must confirm whether the low-noise version is needed and the available supply voltage. |

How do we supply Crouzet in Romania?
We state openly what we confirm for Crouzet motors: the electrical and mechanical parameters come from the French manufacturer's technical documentation, and the exact availability is checked with every order. We bring Crouzet motors on order through EU supply channels, usually within 1–4 weeks of confirmation. For a correct quotation we need the motor type (brushed or brushless), the required torque and speed, the supply voltage and, where applicable, the industry-specific certification requirement. We do not promise permanent availability for specially configured programmable variants.
Software programming of the SMi21/SMi22 motors for the customer's final application is done outside our quotation; aerospace- or rail-certified variants are ordered on request.
Frequently asked questions about Crouzet
What is the difference between the Crouzet SMi21 and SMi22 motors?
The SMi21 has a 57 mm frame and covers power between 66 and 150 W, with an integrated 4096-point encoder and the option of programming through dedicated software. The SMi22 uses a larger 75 mm frame, reaching power of up to 600 W. The choice depends on the torque and power required.
Do you supply Crouzet motors in Romania?
Yes, we bring in brushless motors and brushed DC motors from the Crouzet range on order, from the Hall Effect series to the programmable SMi21 and SMi22 variants. Crouzet motors are not part of our current stock; we source them on order, and the typical publicly stated lead time is between two and four weeks. It helps to specify the power, speed and flange type required for mounting.
What should be specified for a Crouzet motor quotation?
We need the power or torque required by the application, the available supply voltage and the desired working speed, as well as the mounting type or flange existing on the equipment. If precise positioning is needed, it also matters whether an integrated encoder or an electromagnetic holding brake is wanted. This information allows the choice between the brushless and the brushed motors in the Crouzet range.
What does the Low Noise series mean for Crouzet DC motors?
The Low Noise series comprises brushed DC motors built for a reduced noise level, around 35 dBA for the 42 mm version. They are available in 42 and 63 mm frames, and the 63 mm version has a service life of up to 5,000 hours. They are chosen for equipment installed in spaces where operating noise matters.
How do I request a Crouzet quotation?
