Who is TechTop and what does it make?

TechTop is a Chinese electric motor brand headquartered in Shanghai: IEC and NEMA three-phase asynchronous motors with aluminium or cast iron frames, single-phase capacitor motors, brake motors, multi-speed motors, permanent magnet synchronous motors and high-temperature smoke extraction motors. The range covers frame sizes 56–355 and efficiency classes IE1–IE5. For a quotation, send us the code from the motor nameplate, the power, the number of poles, the mounting form and the voltage.

Three-phase motors with aluminium frames are grouped by efficiency class: T1A, T2A, T3A, T4A and T5A, from IE1 to IE5, plus the MS1, MS2 and MS3 series. For cast iron frames there are T1C, T2C, T3C, T4C and T5C, chosen for heavier industrial environments. Single-phase motors appear in the ML (capacitor start and run) and MY (capacitor run) series, with the ML1, ML2, MY1 and MY2 variants by efficiency class. MSB are brake motors, MSD are multi-speed motors, while EC and ECI are permanent magnet synchronous motors, with the ECI having an integrated drive.

Production takes place at three manufacturing bases, in Pudong and Nanhui, in Shanghai, and in Ningde, in Fujian province. When replacing a TechTop motor fitted to pumps, fans, compressors or conveyors, it is important to keep the power, the frame size, the mounting form, the voltage and the efficiency class required by the machine.

What do we supply from the TechTop range?

Product	Description
T3A / T4A / T5A	Three-phase asynchronous motors with aluminium frames, in efficiency classes IE3, IE4 and IE5. They are the general-purpose motors for pumps, fans and conveyors, in IEC construction, and are chosen by power, number of poles, mounting form and the efficiency class required.
T3C / T4C / T5C	Three-phase asynchronous motors with cast iron frames, in efficiency classes IE3, IE4 and IE5, chosen for heavy industrial environments with dust, moisture or vibration. They are fitted to pumps, compressors, large fans and conveyors and are chosen by power, poles and mounting form.
ML / MY	Single-phase capacitor motors: ML with capacitor start and run and MY with capacitor run, in the ML1, ML2, MY1 and MY2 variants by efficiency class. They are used where there is no three-phase supply, on small pumps and fans.
EC / ECI	Permanent magnet synchronous motors; the ECI series has the drive integrated in the motor. They are used in adjustable-speed applications where efficiency at partial load matters, for example on fans and circulation pumps.

Why TechTop?

Efficiency classes IE1–IE5 — from T1A to T5A in aluminium and from T1C to T5C in cast iron
Frame size range 56–355 — from small aluminium motors to large motors with cast iron frames
IEC and NEMA standards — the same brand covers European machines and machines built for the American market
Special variants — MSB brake motors, MSD multi-speed motors and S-TC smoke extraction motors
Permanent magnet motors — the EC series, and the ECI with integrated drive, for adjustable speed

How do we supply TechTop in Romania?

We can quote TechTop three-phase motors from the T3A, T4A, T5A, T3C, T4C and T5C series, MS aluminium motors, ML and MY single-phase motors, MSB brake motors and EC permanent magnet motors. To quote the right motor, send us the code from the nameplate, the power, the speed or number of poles, the frame size, the mounting form (B3, B5, B14), the voltage and the efficiency class required. We supply TechTop motors by import, to order, usually in 1–4 weeks; for large cast iron motors, depending on brand and specifications, the lead time may be longer.

Repair and rewinding of TechTop motors are outside our offer; we quote new motors and equivalent replacements based on the nameplate data.

Frequently asked questions about TechTop

What motors does TechTop make?

TechTop makes IEC and NEMA three-phase asynchronous motors with aluminium (T1A–T5A, MS) or cast iron (T1C–T5C) frames, ML and MY single-phase motors, MSB brake motors, MSD multi-speed motors, EC and ECI permanent magnet motors and S-TC smoke extraction motors, in frame sizes 56–355.

How do I choose the efficiency class for a TechTop motor?

The class is chosen according to the legal requirement for the power and type of motor and according to how many hours a year it runs. The T3, T4 and T5 series correspond to classes IE3, IE4 and IE5, in aluminium (A) or cast iron (C). Send us the power, the number of poles and the operating hours, and we will propose the suitable series.

How long do we wait for a TechTop motor we order?

TechTop motors are delivered in 24–72 h when the item is available locally or at the supplier, and those brought in by import to order usually in 1–4 weeks. For large cast iron motors or special versions, depending on brand and specifications, the lead time may be longer.

Can I replace a TechTop motor on an imported machine with an identical one?

Yes, as long as we keep the frame size, power, speed, mounting form and voltage. We need a photo of the nameplate, the shaft diameter and length and, for flange motors, the flange diameter. With these we quote the same TechTop type or a variant with a higher efficiency class, with the same mounting dimensions.

What do I send for a TechTop motor quotation?

Send the full code from the nameplate, the power in kW, the number of poles, the frame size, the mounting form (for example B3, B5 or B35), the voltage and mains frequency and the efficiency class wanted. For brake motors we also need the brake voltage.

How do I request a TechTop quotation?

Send the TechTop code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
