(1) Coils at maximum temperature, 130 °C (266 °F), mounted to an aluminium heat sink whose area is noted in table on page 69
, and at 40 °C (104 °F) ambient.
(2) Continuous force and current based on coil moving with all phases sharing the same load in sinusoidal commutation.
(3) For standstill conditions, multiply continuous force and continuous current by 0.9.
(4) Calculated at 20% duty cycle for 1.0 second max. Some applications may produce significantly higher peak forces. Call Applications Engineering (631.344.6600) for details.
(5) Winding parameters listed are measured line-to-line (phase-to-phase).
(6) Currents and voltages listed are measured 0-peak of the sine wave unless noted as rms.
(7) Specifications are ±10%. Phase-to-phase inductance is ±30%.
(8) All specifications are at the standard reference air gap as shown in the drawing on page 73
and page 75.
