What is the difference between a Techtop TAI 71A and 71B frame?

Both 71A and 71B are frame variants within the Techtop TAI series. According to Techtop, the difference between the A and B variants relates to the motor's internal design and performance requirements rather than the external mounting dimensions. This means the same TAI 71 dimensional drawings can be used for the corresponding 71A and 71B motor variants.

Please note that the “B” in 71B does not mean TAIB. TAIB is Techtop's separate brake motor series, while 71A and 71B are frame variants within the standard TAI series.

Is the Techtop TAI 0.09kW motor single phase or three phase?

This is a three phase electric motor from Techtop's TAI aluminium motor range.

What speed does the Techtop TAI 0.09kW 8 pole motor run at?

This is an 8 pole motor with a full-load speed of approximately 665 RPM. It is designed for applications requiring considerably lower motor speeds than typical 2 pole or 4 pole motors.

What frame size is this motor?

This motor uses a 71A frame. When replacing an existing motor, always compare the frame dimensions, shaft size and mounting configuration rather than selecting a replacement based only on its kW rating.

What is the shaft diameter?

The Techtop TAI 71A frame motor has a 14mm shaft diameter. The shaft dimensions should always be checked against the existing coupling, pulley or driven equipment before installation.

What is the full-load current?

The motor has a full-load current of approximately 0.53A at 400V.

How much torque does this motor produce?

The Techtop TAI 0.09kW 8 pole motor produces approximately 1.29Nm of torque at full load.

Is this motor suitable for continuous operation?

Yes. The Techtop TAI range is designed for S1 continuous-duty operation when the motor is correctly selected, installed and operated within its rated specifications.

What protection rating does this motor have?

The standard TAI motor has an IP55 protection rating and TEFC (Totally Enclosed Fan Cooled) construction. It also features Class F insulation with Class B temperature rise.

What mounting options are available?

Techtop TAI motors are available in several common mounting configurations, including B3 Foot Mount, B5 Flange Mount, B14 Face Mount, B34 Foot & Face Mount and B35 Foot & Flange Mount. Select the mounting configuration that matches your equipment and installation requirements.

Can this Techtop motor replace another brand of electric motor?

Potentially, yes. When selecting a replacement motor, compare the power rating, voltage, number of poles, RPM, frame size, shaft diameter, mounting configuration and physical dimensions with the existing motor. Matching the kW rating alone does not guarantee that a replacement motor will fit or operate correctly.

What applications is an 8 pole 665 RPM motor suitable for?

An 8 pole motor may be suitable for applications requiring relatively low motor speed, including certain fans, ventilation equipment, conveyors and industrial machinery. Suitability depends on the torque, speed, mounting and other requirements of the driven equipment.

Are dimensional drawings available for this motor?

Yes. Dimensional drawings are available to help confirm the shaft, foot mounting, flange, face mounting and overall motor dimensions. The same TAI 71 dimensional drawings can be used for corresponding 71A and 71B frame variants.

Is a motor data sheet and test report available?

Yes. Technical documentation is available to assist with checking the motor's performance and specifications before purchase.

How can I confirm whether this motor will fit my machine?

If you are unsure which motor you require, contact Paddle Wholesale Australia and provide a clear photo of the existing motor's nameplate, shaft and mounting arrangement. Where possible, also provide the important mounting and shaft dimensions so the specifications can be compared.
