Wan jak mawdaw ni hpe madung hku nna battery, wan jak motor, controller ni hte galaw ai.
1. Battery: Battery gaw wan jak mawdaw a n-gun npawt rai nna, shi a bungli galaw ai lam gaw mawdaw a n-gun atsam hpe hkrak sha hkra machyi shangun ai. Ya aten hta, lithium-ion battery ni gaw, n-gun grai law ai hte lawan ai hku charge galaw lu ai majaw, wan jak mawdaw ni a matu, madung battery amyu rai nga ai.
2. Motor: Motor gaw wan jak mawdaw a madung daw rai nna, battery a wan n-gun hpe jak n-gun de galai shai ya nna, mawdaw hpe shawng de sa wa shangun ai lit nga ai. Teng sha ra kadawn ai lam hta hkan nna, wan jak mawdaw ni gaw DC mawdaw, AC asynchronous mawdaw, permanent magnet synchronous mawdaw zawn re ai mawdaw amyu myu hpe lang mai ai. Permanent magnet synchronous motor ni gaw, shanhte a n-gun grai ja ai hte grai kaja ai hku hkang lu ai majaw, wan jak mawdaw hpaga lam hta grai lang ma ai.
3. Controller: Controller gaw wan jak mawdaw a "brain" rai nga ai. Dai gaw mawdaw a mawdaw gau ai masa hte mawdaw gau ai wa a ningmu hpe madung tawn nna, shim lum ai hte ngang grin ai hku galaw lu na matu, mawdaw hpe hkrak hkrak hkang lu ai. Dai controller gaw battery hpe grai n-gun dat ai hte grai n-gun dat ai kaw na mung makawp maga ya ai majaw, battery a asak hpe galu shangun ai.
