MIL-PRF-62361E
2. Five seconds with driving torque exceeded and the clutch slipping for type I
and II motors.
3. Plug reversal by the application of voltage of the opposite polarity to that
imposed on the motor (see 3.3.1.5).
4. Five seconds transmitting torque in the opposite direction at rated torque.
4.5.10 Insulation resistance. To determine conformance 3.3.1.7, the insulation
resistance of the motor shall be measured prior to installation of the EMI filter. Insulation
resistance shall be tested as specified in MIL-STD-202, method 302, condition B, conducted at
500 V dc, and measured between winding and case.
4.5.11 Dielectric withstanding voltage. To determine conformance to 3.3.1.8, prior to
installation of the EMI filter, the motor shall be subjected to dielectric withstanding voltage in
accordance with MIL-STD-202, method 301. The voltage shall be 500 V rms, 60 Hz, for one
minute; or 600 V rms, 60 Hz, applied for one second between winding and frame.
4.5.12 Lead strength. To determine conformance to 3.3.1.9, the motor and filter ends
shall be attached to a spring scale and a force of 22 N shall be applied for one minute. The test
shall be applied at random direction with respect to the exit location of the wire from the motor
and the attachments of wire to the filter.
4.5.13 Dimensions. To determine conformance to 3.3.1.10, the motor dimensions
affecting interchangeability shall be determined by examination.
4.6 Environmental tests.
4.6.1 Temperature.
4.6.1.1 High (operating). To determine conformance to 3.4.1.1, the motor shall be tested
in accordance with MIL-STD-810, method 501.3, procedure II. Temperature shall be 60°C.
4.6.1.2 High (nonoperating). To determine conformance to 3.4.1.2, the motor shall be
tested in accordance with MIL-STD-810, method 501.3, procedure I. Temperature shall be
70°C.
4.6.1.3 Low (operating). To determine conformance to 3.4.1.3, the motor shall be tested
in accordance with MIL-STD-810, method 502.3, procedure II. Temperature shall be -32°C.
4.6.1.4 Low (nonoperating). To determine conformance to 3.4.1.4, the motor shall be
tested in accordance with MIL-STD-810, method 502.3, procedure I. Temperature shall be
-54°C.
