1.1 Motor electrical input
•
•
•
It was assumed that the nominal bus voltage to the drive was 400VDC
The drive is a sinusoidal drive where the voltage supplied to each phase leg is
½ the bus voltage.
Maximum available continuous phase current = 35 Amps RMS (49.5 Apk)

•
Gearbox: Spinea TS 110‐33
Gearbox Friction: .24Nm
Gearbox Max input speed: 3500 rpm
1.3 Motor output speed/torque Requirements
The minimum required continuous geared output torque at 0 rad/sec is
80Nm. The minimum required peak geared output torque is output power at
12 rad/sec is 160Nm.

1.4 Torque Constant Vs Current
The Figure bellow shows the motor torque constant as a function of phase
current. At a sinusoidal current of 28 RMS Amps the torque constant falls off
by 10% from its low current value.

Motor Heating
The motor heating is shown below. The heating shown is based on the
assumption that the motor winding temperature is 100°C. The heating includes
iron losses and the specified gearbox friction.

Torque Speed Performance
Figure bellow shows the motor performance with the current amplitude
limit set to 23Amps (16.3 RMS Amps). There is margin in meeting peak
torque requirement.

Motor Thermal Performance
Continuous
The estimated thermal resistance from winding to atmosphere for this motor
is approximately 1.0°C/Watt. This means that the continuous allowable
wattage, assuming a 150°C maximum winding temperature and a 70°C
ambient, is 80 Watts.
Short Duty Cycle
The following short term currents and temperature rises occur:
At 49Apk, 35 Arms (=370Nm geared output torque), the motor winding
temperature will rise 80°C within 2 seconds.
At 98Apk, 70Arms (660Nm geared output torque), the motor winding
temperature will rise 40°C within 0.250 second.
