Maximal, for a period of two seconds permissible torque. This torque is available for dynamic strain of the motor and refers to the below defined peak motor current and a magnet temperature of 20°C.
Continuous torque (water cooling, 100°C):
Continuously available torque with cooling temperature of 20°C. This torque is made available by the motor with a permanent strain on all three phases. This implies that the motor frequency based on a continuous revolution is at least 2 Hz. For a calculation of the speed, the motor frequency is divided by half the number of the magnetic poles.
Stall torque (water cooling, 100°C):
In standstill the motor has a load independant direct current. This is the reason why in standstill only torque is available which is reduced by square root2. In frequent motor operation in standstill or with very low speed, one must consider that the strain of the single phases can be very different and that the temperature can differ significantly from phase to phase.
Peak power dissipation:
Power dissipation with peak torque and coil temperature of 20°C.
Continuous power dissipation:
Power dissipation of the motor with 100°C coil temperature and continuous torque.
The motor constant is represented by the relationship of continuous torque with the square root of the power dissipation with the actual torque. This constant is related to a coil temperature of 20°C.
Electrical time constant:
Electrical time constant, representing the relationship of inductivity with the coil resistance of a motor phase.
The thermal resistance indicates the increase of temperature per power dissipation. The indicated value applies for a permanent strain on all phases and a coil temperature of 100°C.
Number of magnetic poles:
Number of magnetic poles of the rotor. The product of half the pole number and speed indicates the frequency of motor current.
The moment of inertia refers to the resistance of the moving rotor in relation to a modification of its rotational speed.
