Generator Indonesia — Components & Alternators for Genset Builders
Indah Machine supplies generator components to genset builders, integrators, and maintenance shops in Indonesia. We do not assemble complete diesel gensets — instead, we provide the alternator heads (UCW, TZH, T2W3, Mecc Alte) and electrical components that go into your genset build. Based in Medan with warehouse coverage in Jakarta and Surabaya.
Alternator heads for your generator builds
Alternator · UCW
UCW Series Brushless Synchronous Alternator
Brushless synchronous alternators covering 37.5–1250 kVA at 1500 rpm and 200–875 kVA at 1000 rpm. High efficiency, low waveform distortion, and rugged construction for prime or standby generator sets.

Why genset builders and integrators choose Indah Machine
Indah Machine has supplied alternators, electric motors, and power presses to Indonesian industry for over 50 years. We support sizing, installation, commissioning, and after-sales — backed by stock in Medan with shipping to Jakarta, Surabaya, and across Indonesia.
FAQ for generator builders
Do you sell complete diesel gensets?
No. Indah Machine focuses on the alternator head and components side of the build. We supply alternators, electric motors, and power presses — not the diesel engine or full genset enclosure.
Which alternator series matches a typical 100 kVA prime-power genset?
The UCW-100-1500 or equivalent TZH-100 brushless synchronous alternator is the typical match for a 100 kVA prime-power 1500 RPM genset at 400/230V 50 Hz. We can confirm based on your engine spec.
Can I order multiple alternators for a project?
Yes. Project quantities are welcome — share the project schedule and we can plan stock and delivery from Medan, Jakarta, or Surabaya.
Do you provide technical drawings?
Yes. Each series has a technical PDF catalog (downloadable on the product detail page) and we can provide additional drawings on request.
What about generator parts other than alternators?
Contact us with the parts list and we will advise what we stock or can source.
