The Motor converts electrical energy into mechanical energy (rotational motion) and losses
are converted into heat energy. Since, these are compact motors and have less surface area
which is required for cooling, they tend to heat more. The temperature of 30°C ~ 40°C above
ambient is ok. i.e. If ambient temperature is 40°C, then motor temperature of 70°C is
normal. The temperature of motor of continuous duty stabilizes after around one hour of
working.
In case of doubt, please check current drawn by the motor. It should be less than or equal to the Rated Current

Even if no load is attached to the motor, it consumes certain minimum current which is almost fully converted to heat energy. Hence the motor gets heated.

The torque produced by the motor is affected by changes in power supply voltage. The
torque produced by the motor is proportional to roughly the square of the power supply
voltage. For example, if the voltage of a motor rated at 230 V fluctuates between 207 V
(90%) and 253 V (110%), the torque produced will vary between 80% and 120%. When using
motors under large power voltage fluctuations, remember that the torque produced will vary,
so select a motor that provides a sufficient margin.
A reversible motor is not simply an induction motor with a simple braking mechanism added.
The ratio of coils between the primary and the secondary coils in a reversible motor is
different from that of an induction motor. The simple brake mechanism is added to the rear
of the motor.
The capacitor's capacitance is also increased to increase the starting torque. This means
that if only the brake mechanism is removed, the reversible motor will not be usable at a
continuous rating like an induction motor; it will simply lose its holding power and its
reversing characteristics will be reduced.
Reversible motors require a larger input power than induction motors to increase the
starting torque and improve the instant reversing characteristics. This means that loss is
high and the temperature rises more during continuous operation. If operated continuously,
the motor will burn out. It is thus designed to provide maximum performance if operation is
restricted to less than 30 minutes continuously.
The speed of single phase (AC) induction motors / reversible motors is determined by the power supply frequency.
To change the speed of induction / reversible motors, the power supply frequency needs to be changed.
If your application requires changing speed, we recommend a speed control motor.
Almost all of Swipfe standard compact AC motors that fall within the broad group of single-phase induction motors are "capacitor-start-capacitor-run-motors".
To run an induction motor, a rotational magnetic field must be created. Capacitors perform the role of creating a power supply with the phase shift that is required for creating such a rotational magnetic field.
Three-phase motors, by contrast, always supply power with different phases, so they do not require capacitors.
The capacitor that comes with the motor has a capacitance that was selected to work optimally with the motor. When another capacitor is used,
it should be a motor capacitor with the same capacitance and rated voltage as the capacitor that comes with the motor.
Gearheads reduce the motor speed by 3 ~ 180. Reduction may be in a single stage or multiple stages.
The number of speed reductions stages depends on the gear ratio, so the direction of output shaft rotation differs.
Extreme changes in temperature may lead to condensation within the motor.
Should this occur, parts may rust, greatly shortening the service life. Take measures to prevent condensation.
A gearhead with a gear ratio of 180 must be connected to two decimal gearheads with a gear ratio of 10.
The permissible torque is the same as if the 180 gearhead were used alone. The mounting screws must also be longer.
Swipfe lubricates the surface of gears in gearheads with grease. Oiling is not required.
In order to turn a single-phase induction motor, it is necessary to use a capacitor to create two power
supplies with different phases to obtain the rotating magnetic field. Therefore, if the capacitor is not properly connected,
the phenomenon described occurs. Check for a cut line or contact defect in the capacitor section. The way to check is to measure
the voltage across the capacitor terminals and check whether or not it is at least 1.5 times the power supply voltage.
If not, the capacitor may not be working properly.
Three points should be kept in mind when using a fan for ventilation and cooling:
1. Do not increase ventilation resistance.
2. Ensure that the air inside the machinery is not stagnant.
3. Do not create any shortcuts for air to pass through, the ideal fan position is where air flows in one direction, without interference. If these conditions are met, there is no fundamental difference between forced ventilation and blow ventilation, but exhaust is more effective in maintaining a stable internal temperature.
