What is the difference between a Techtop TAI 80A and 80B frame?

Both 80A and 80B are frame variants within the Techtop TAI series. According to Techtop, the difference relates to the motor's internal design and performance requirements rather than the external mounting dimensions. The same TAI 80 dimensional drawings can be used for corresponding A and B variants. The “B” frame designation should not be confused with the separate TAIB brake motor series.

Is this Techtop 0.18kW motor single phase or three phase?

This is a three phase electric motor rated for 230/415V at 50Hz.

What speed does this motor run at?

This is a 8 pole motor with a full-load speed of approximately 690 RPM.

What frame size is this motor?

This motor uses a 80A frame. Always compare the dimensional information and mounting arrangement with your existing motor when selecting a replacement.

What is the shaft diameter?

This motor has a 19mm shaft diameter. 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 0.82A at 400V.

How much torque does this motor produce?

The motor produces approximately 2.48Nm of torque at full load.

Is this motor suitable for continuous operation?

Yes. This motor has an S1 continuous-duty rating when correctly selected, installed and operated within its rated specifications.

What protection rating does this motor have?

The motor has an IP55 protection rating and TEFC construction, with Class F insulation and Class B temperature rise.

What mounting options are available?

Common mounting configurations include B3 Foot Mount, B5 Flange Mount, B14 Face Mount, B34 Foot & Face Mount and B35 Foot & Flange Mount.

Can this motor replace another brand?

Potentially, yes. Compare the power rating, voltage, number of poles, RPM, frame size, shaft diameter, mounting configuration and physical dimensions before selecting a replacement.

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