The motor output shaft turns at a defined speed. This speed is generally
too high for the majority of applications.
To reduce this speed we provide users with a complete range of
gearboxes, each equipped with a series of ratios.
As a result, the motors can be used for numerous functions.
➜ Gearbox characteristics
Each gearbox has been designed for a certain workload. We have defined
its potential and its limits for optimum mechanical life.
The principal characteristic is its capacity to absorb a maximum torque in
continuous operation.
The range of gearboxes in this catalogue can be used for maximum
torques of between 0.5 and 6 N.m for long mechanical lives. The values
given are for standard products used in the normal operating conditions
specified.
In certain cases, these values can be increased if the required life is
reduced. Special cases are dealt with by our design staff.
Each gearbox nevertheless has a limit which is the
This torque, applied to the gearbox, can cause its destruction when first
used.
➜ Gearbox construction
Selecting a geared motor
Selection is made in relation to the prospective workload.
Before making a selection, it should be remembered that the motor
absorbs a certain amount of power, the absorbed power and it cannot
deliver more than a fraction of this power : the maximum is defined as the
usable power or the mechanical power.
Usable power links 2 factors.
Analysis of this formula clearly shows the function of the gearbox.
It reduces speed and increases torque since the usable power produced
by the motor is recovered by the gearbox (within the limits of normal
efficiency of course).
The torque requirement thus serves to define the gearbox (characterised
by its maximum torque) and the choice of motor depends on the speed at
which the torque is required.
The usable power should be borne in mind in all cases, as it is the basic
parameter when choosing a motor.

➜ Temperature rise
Permanent magnet motors generally have relatively low efficiency and
some of the lost energy is converted into a rise in the temperature of the
motor.
We consider that this rise in temperature reaches its maximum level after
2 hours of continuous operation.
To calculate the rise, we use the method known as resistance variation.
R =
R’ = Resistance of the same coil after 2 hours of continuous motor
T1 = Ambient temperature at the end of the test.
Ta = Ambient temperature at the beginning of the test.
➜ Dielectric strength
All our products are tested to current standards.
➜ Insulation resistance
This is greater than or equal to 75,000 M
current in conditions of ambient temperature and humidity.
➜ Safety
Crouzet synchronous motors are designed and manufactured for
integration into equipment or machines meeting, for example, the
requirements of the Machinery standard : EN 60335-1 (IEC 335-1) :
Safety of domestic electrical appliances.
Integration of Crouzet synchronous motors into appliances or machines
should, as a rule, take into account the following motor characteristics :
Our motors are in general designed to conform to international
recommendations (IEC), American standards (UL - CSA) and/or
European standards (EN).
Proof of compliance with these standards and recommendations is
demonstrated by an approval (a mark or certificate of conformity granted
by an accredited body) or the manufacturer’ s declaration of conformity
(drafted in accordance with ISO/IEC 22 guidelines).
➜ EC directives
Our motors are compatible with European Community directives (Low
voltage 73/23 > 50 VAC) and in particular the aspects of electrical
safety referred to in the above standard EN 60335 (domestic electrical
appliances).
The «CE» mark on all our products is proof of this conformity.
Moreover, our products are particularly suited, for example, to applications
concerning both office equipment and medical equipment covered by
standards EN 60601 and EN 60950 respectively.
➜ Environmental protection
The modern concept of protection of the environment is an integral part of
our motors, from product design through to packaging.
Both asynchronous and synchronous motors and geared motors designed
for integration into more complex equipment by professionals, rather than
end users, are excluded from the areas of application of this directive.
Crouzet will however be pleased to provide the EMC characteristics of its
products on request.
