GLOSSARY GL
Glossary
AWG American Wire Gauge is a standard for wire thickness specification. The diameter “d” can be calculated with the AWG value “n”.
d[mm]= 0.127[mm] x 92 ^((36-n)/39).
Back EMF Phase-Phase_peak B
emf
V/m/s Back electromotive force. A linear motor, when operated, also acts as a generator. The Back EMF describes the coefficient
between the generated voltage and the speed of the motor [V/m/s]. When the generated Voltage is nearly equal to the bus
voltage of the system the motor can not run any faster.
Beding radius Static minimum Minimum bending radius for the cable when used in static configuration.
Bending radius Dynamic minimum Minimum bending radius for the cable when used in dynamic configuration.
Cable Life (Power FLEX) Number of operating cycles for use in powerchains. Only applicable for coils with a FLEX cable. The specified value is for a
temperature range of -5 to 90°C and with the cable configured with the minimum bending radius for flexible applications.
Cable mass length 1m m kg/m Mass of both cables.
Coil unit length excluding
cables L mm Length of the coil unit.
Coil unit weight excluding
cables W Kg Weight of the coil unit without the cable.
coils @ 100°C The coil temperature where the specifications are rated at.
Continuous current air cooled coils @ 100°C I
c
Arms The continuous current [A] the motor can be run at to achieve the continous force when cooled by means of radiation, convection
and conduction through a 20°C aluminium reference surface and a thermal resistance of 0.05[K/W] .
Continuous current water cooled coils @ 100°C I
cw
Arms The continuous current [A] the motor can be run at to achieve the continous force when water cooled.
Continuous force coils @ 100°C F
c
N see Continuous force air cooled.
Continuous force air cooled coils @ 100°C F
c
N The continuous force for a non water cooled coil. At continuous force the heat gain and dissipation in the coil are equal.
Dissipation occurs purely via conduction, convection and radiation. Tecnotion’ linear motors continous force is specified for a
mounting surface at 20°C. The thermal resistance is 0.05K/W when mounted to a aluminium heatsink.
Continuous force water cooled coils @ 100°C F
cw
N At continuous force the heat gain and dissipation in the coil is equal. For Tecnotion linear motors the mounting surface needs to
be at 20°C. The thermal resistance for watercooling is 0.02K/W when combined with an aluminium heatsink.
Electrical time constant coils @ 25°C τ
e
ms The time after which the current reaches 63%(1-(1/e)) of the desired magnitude. This metric gives an indication of the reaction
time of the motor.
Induction per phase I<0.6 Ip L
ph
mH The Induction value in [milli Henry] of one phase or winding of the coil. This value can be verified via the motor cables. The
double value will be measured because of the star point configuration of the phases / windings.
KTY temperature sensor Ohm/C The temperature sensors for the Iron core series. Has a positive coefficient between temperature and resistance.
