PPD Series motors

CMG's PPD range of Ex d "flameproof" motors are certified for use in Class I Zone I hazardous locations. These motors are designed to contain any sparks within the motor without igniting external vapours. They incorporate features such as a robust cast iron construction and integral terminal box to meet the stringent certification requirements.

The complete PPD range covers sizes 80 to 280, three phase 2, 4, 6 & 8 pole, with foot and flange mounting options.

Certification The PPD range is specially designed and certified for use in a CLass I Zone I, Group IIA&B, temperature T4, EX d area. SAA certification numbers are AUS Ex 3767X, AUS Ex 3768X, and AUS Ex 3769X for frames 80 to 100, 112 to 180, and 200 to 280 respectively.

Certification

The PPD range is specially designed and certified for use in a CLass I Zone I, Group IIA&B, temperature T4, EX d area. SAA certification numbers are AUS Ex 3767X, AUS Ex 3768X, and AUS Ex 3769X for frames 80 to 100, 112 to 180, and 200 to 280 respectively.

Mines Department Approval (MDA)

The range of PPD motors are approved for use in coal mines. This approval forms part of the main certification.

Standards and Specifications

The main dimensions and rated outputs of the PPD series generally conform to Australian Standard AS/NZS1359 (CENELEC kW-frame size allocation table) and International Standards IEC 60034 and IEC 60072. In addition the motor enclosure and temperature rise are tested to comply with AS2380.2-1991.

Operating parameters

PPD series motors are designed with the following parameters:

Continuous duty (S1)
Three phase 415 volts, 50 Hz power supply
Ambient temperatures up to 40°C
Installation at altitudes up to 1000 metres

Insulation class F, T4 surface temperature

PPD series motors have class F insulation and class B temperature rise. This design feature assures cool running of the motor. Certified Ex d T4 motors have a maximum allowable surface temperature of 135°C.

MEPS compliance

PPD motor efficiency levels comply to the Minimum Efficiency Requirements as per AS/NZS 1359.5:2000.

Degree of protection

Level of enclosure protection for the PPD series is IP 56.

Paint finish

Motors are painted with a high quality enamel finish. The standard colour is grey, with other colours available on request.

Bearings

Bearings fitted are deep groove ball type and are the same size for both ends. Frames 80 to 132 are fitted with shielded bearings that are lubricated for life. Frames 160 to 280 have relubricatable bearings.

Terminal box

The terminal box of the PPD series is integral to the body of the motor, is amply sized to allow for termination of cables, and has a single conduit entry designed to accept a flameproof gland.

Internal connections

PPD motors have three terminals for DOL starting.

VF drive selection

All EX d hazardous location motors require temperature limiting devices (eg thermistors) fitted when used in conjunction with VF drives to ensure their temperature rise remains below the certified T4 level. Ex d motor VF drive packages are available from CMG.
