SLA Series motors

The SLA series motor range is built in an all aluminium frame which has the same enhanced performance and electrical design as the cast iron SGA series that has been specified by the Australian industry for over a decade.

Features
Standards and specifications The main dimensions and rated outputs of the SLA series generally conform to Australian Standard AS1359 and International Standards IEC 60034 and IEC 60072. Multi-mount feature The standard SLA motor is supplied with the terminal box top mounted, and has detachable feet. The unique multi-mount design allows the motor feet to be removed and the motor mounted from any of the 16 mounting pads. This feature means that for axial flow fans, there is no need for a motor mount in the fan case, which enables quicker assembly times, lower cost and less restriction to air flow. Alternatively the feet may be relocated to either side, for a wall mounted motor or side mounted terminal box. Operating parameters Standard SLA series motors are designed with the following parameters: Continuous duty (S1) Three phase 380-420 Volts, 50 Hz power supply Ambient temperatures up to 40°C Installation at altitudes up to 1000 metres Insulation class F, Temperature rise class B SLA Series motors have class F insulation and class B temperature rise which gives them good service factor capabilities. Degree of protection Standard level of enclosure protection for the SLA series is IP 55, with increased ratings available on request. MEPS compliance (Eff 2) SLA motor efficiency levels comply to the Minimum Efficiency Requirements as per AS/NZS 1359.5:2000 (equivalent to European Standard Eff 2)	Pump application A locked drive end bearing is standard on all SLA flange mounted motors from 90 to 160 frame. This makes it perfect for pump applications where minimal axial shaft movement is critical to provide tight tolerances for impellers. On request CMG can provide a locked bearing option for smaller frame sizes and foot mounted motors. Air movement application Low weight design and the standard drilled and tapped hole in the shaft makes the SLA series ideally suited for all air movement applications. Paint finish Motors are painted with a high quality enamel finish. The standard colour is dark blue (RAL5010), with other colours available on request. Bearings Bearings fitted are a deep groove ball type with double seals and are the same size for both ends. Terminal box The terminal box of the SLA series is separate from the body of the motor allowing it to be rotated providing ease of connection to supply. Internal connections, Voltages and VF drive selection Standard terminal connections for motors 3kW and below is 240 Volt Delta / 415 Volt Star. These motors are suitable for operation with 240 Volt three phase Variable Frequency Drives or 415 Volt DOL starting. Standard terminal connections for motors 4kW and above is 415 Volt Delta / 720 Volt Star. These motors are suitable for operation with 415 Volt three phase Variable Frequency Drives, 415 Volt Star/Delta or 415 Volt DOL starting.

Standards and specifications

The main dimensions and rated outputs of the SLA series generally conform to Australian Standard AS1359 and International Standards IEC 60034 and IEC 60072.

Multi-mount feature

The standard SLA motor is supplied with the terminal box top mounted, and has detachable feet.
The unique multi-mount design allows the motor feet to be removed and the motor mounted from any of the 16 mounting pads. This feature means that for axial flow fans, there is no need for a motor mount in the fan case, which enables quicker assembly times, lower cost and less restriction to air flow.
Alternatively the feet may be relocated to either side, for a wall mounted motor or side mounted terminal box.

Operating parameters

Standard SLA series motors are designed with the following parameters:

Continuous duty (S1)
Three phase 380-420 Volts, 50 Hz power supply
Ambient temperatures up to 40°C
Installation at altitudes up to 1000 metres

Insulation class F, Temperature rise class B

SLA Series motors have class F insulation and class B temperature rise which gives them good service factor capabilities.

Degree of protection

Standard level of enclosure protection for the SLA series is IP 55, with increased ratings available on request.

MEPS compliance (Eff 2)

SLA motor efficiency levels comply to the Minimum Efficiency Requirements as per AS/NZS 1359.5:2000 (equivalent to European Standard Eff 2)

Pump application

A locked drive end bearing is standard on all SLA flange mounted motors from 90 to 160 frame. This makes it perfect for pump applications where minimal axial shaft movement is critical to provide tight tolerances for impellers. On request CMG can provide a locked bearing option for smaller frame sizes and foot mounted motors.

Air movement application

Low weight design and the standard drilled and tapped hole in the shaft makes the SLA series ideally suited for all air movement applications.

Paint finish

Motors are painted with a high quality enamel finish. The standard colour is dark blue (RAL5010), with other colours available on request.

Bearings

Bearings fitted are a deep groove ball type with double seals and are the same size for both ends.

Terminal box

The terminal box of the SLA series is separate from the body of the motor allowing it to be rotated providing ease of connection to supply.

Internal connections, Voltages and VF drive selection

Standard terminal connections for motors 3kW and below is 240 Volt Delta / 415 Volt Star. These motors are suitable for operation with 240 Volt three phase Variable Frequency Drives or 415 Volt DOL starting.
Standard terminal connections for motors 4kW and above is 415 Volt Delta / 720 Volt Star. These motors are suitable for operation with 415 Volt three phase Variable Frequency Drives, 415 Volt Star/Delta or 415 Volt DOL starting.
